1) Build shit! Get an account on Google App Engine, and start launching real web apps, with real CRUD features.
2) AVOID JQUERY. Try as much as you can to write javascript with 0ut Jquery. Jquery is a way overbloated API and you’ll spend too much time learning it instead of javascript. document.querySelector() will work just fine!
3) Post every bit of code you write on GitHub, and try to convince people/friends smarter than you to read it and give you advice.
4) Seek failure, and just keep learning!

Good luck, Simpliv 🙂

What Does JavaScript Do? 10 things to learn on the way to becoming a JavaScript Master

JavaScript is one of the world’s most popular programming languages, primarily used to add automation, animations and interactivity to Web pages. Web developers use JavaScript for anything from automating simple tasks to creating complex Web pages that behave like desktop software applications. JavaScript is also used beyond the Web in software, servers and embedded hardware controls.

Run JavaScript in Web Pages

Used in Web pages, JavaScript is a “client-side” programming language. This means JavaScript scripts are read, interpreted and executed in the client, which is your Web browser. By comparison, “server-side” programming languages run on a remote computer, such as a server hosting a website. The client-side nature of JavaScript allows developers to add interactive features that change and update a Web page without reloading a new copy of the page from the website.

Implement Basic Automation

In addition to standard programming language features, such as text manipulation and math calculations, JavaScript can access a wealth of information about the browser and the Web page it runs in. JavaScript can use this information to write a custom greeting based on the time of day, add the Web page address in the page footer and optimize the Web page based on the browser you are using.

Update Web Page Content on the Fly

Two important features give JavaScript the power to change a Web page on the fly as you are interacting with it. First, JavaScript is “event-driven,” meaning it can respond to events such as mouse clicks, keyboard input, a Web page loading or a timeout being reached. Second, JavaScript has access to the Document Object Model (DOM), an interface to the structure of a Web page. This gives JavaScript access to read and change images, text, form fields, styles, and other elements and attributes of a Web page.

Events and the DOM interface allow JavaScript developers to perform practical tasks, such as validating form input, as well as add interactive features, such as image sliders and games. These are central to the implementation of Dynamic HTML (DHTML).

Communicate with the Cloud

Using Asynchronous JavaScript + XML (Ajax), JavaScript can exchange data with a server. This provides the potential to leverage server-side resources to build powerful Web applications. With Ajax, JavaScript can access computing power, data and specialized server resources that are impractical or impossible to provide in a purely client-side application. For example, Ajax can be used to create form fields that provide suggestions as you type, display search results without reloading the Web page, and provide interactive maps you can explore with a swipe of your mouse cursor.

Know the Benefits and Drawbacks

JavaScript is one of the tools Web developers use to save time with automation, attract website visitors with compelling features and improve the user experience. Developers use JavaScript to add functionality without the need to maintain and support browser-specific add-ons. JavaScript can be used to implement rich Web applications without requiring special software.

However, there is the potential for security issues. JavaScript engine vulnerabilities, Cross-site Scripting (XSS), Cross-site Request Forgery and other exploits can expose website visitors and Web servers to attacks that may compromise sensitive data or damage computing systems.

Potentially, a JavaScript vulnerability could be used to steal your files and private browser data, or install malicious software on your computer. Keep your operating system and browser up-to-date. Protect your computer with antivirus software. Secure your browser by adjusting settings to use high security levels, turn on warnings and prompts, and disable ActiveX and Java. Use care when following links, entering personal information, downloading files and allowing scripts to run.

10 things to learn on the way to becoming a JavaScript Master

I guess you are a web developer. Hopefully you are doing fine and you have a great job, maybe you are even self-employed or working as a freelancer. The future of the field looks great. Maybe you are just starting out as a web developer, maybe you have been working as a programmer for a longer period already. However comfortable you are with JavaScript, it is always good to get a refresher on some topics to read up about or get them on the radar in the first place. Here are 10 things you definitely have to learn before you can call yourself a master in JavaScript.

1. Control Flow

Probably the most basic topic on the list. One of the most important, maybe the most important one. If you do not know how to proceed with your code, you will have a hard time. Knowing the ins and outs of basic control flow is definitely a must.

• if else — If you don’t know these, how did you write code before?
• switch — is basically if else in a more eloquent way, use it as soon as you have multiple of different cases.
• for — Do not repeat yourself, this is what loops are for. Besides the normalfor -loop `for of` and for in come in very handy. The big advantage of for -loops is that they are blocking, so you can use async await in them.
• Advanced conditionals — Using the ternary and logical operators can make your life a lot easier, especially when you try to do things inline, meaning that you don’t want to save values to use them later. Example:

// ternaryconsole.log(new Date().getHours() < 12 ? 'Good Morning!' : 'Time for a siesta')
// logical operatorsconst isJsMaster = prompt('Are you a JavaScript master?') === 'true'
console.log(isJsMaster && 'proficient coder')

2. Error handling

This took a while for me. It does not matter if you are working on frontend or backend, the first year or so, you will probably default to console.log or maybe console.error for ‘handling’ errors. To write good applications, you definitely have to change that and replace your lazy logs with nicely handled errors. You may want to check out how to build your own Error constructor and how to catch them correctly, as well as showing the user what the actual problem is.

3. Data Models

Similar to moving through your application continuously, you have to decide where to group specific information chunks and where to keep them separate. This does not only apply to building database models, but also function parameters and objects or variables. Example:

const calcShape = (width, height, depth, color, angle) => {...}const calcShape = ({width, height, depth, color, angle}) => {...}

4. Asynchronity

This is a very important aspect of JavaScript, Either you are fetching data from the backend or you are processing requests asynchronously in the backend itself. In pretty much all usecases, you will encounter asynchronity and its caveats. If you have no idea what that is, you will probably get a weird error, which you will try to fix for a couple of hours. If you know what it is, but you don’t really know what to do about it, you will end up in callback-hell. The better approach is to use promises and/or async await in your apps.

5. DOM Manipulation

This is an interesting topic. Normally it is somewhat left out in the day today life as a developer. Maybe you learned jQuery and never felt the need to pick up some native DOM manipulation skills, maybe you are just using a frontend framework, where there is rarely a need for custom DOM manipulation. However, I think this is a crucial part of understanding JavaScript, at least in the frontend. Knowing how the DOM works and how to access elements gives you a deep understanding of how websites work. In addition, there will be the point where you have to do some custom DOM manipulation, even when you use modern frontend frameworks, and you definitely do not want to put jQuery in your package.json just to access an element.

6. Node.js / Express

Even as a frontend developer, you should know the basics of node.js. Ideally, you would also know how to spin up a simple express server and add some routes or change existing ones. JavaScript is great for writing scripts to help you automate a lot of tasks. Therefore, knowing how to read files, work with filepaths or buffers gives you a good toolset to build anything.

7. Functional Approach

There is an everlasting debate about functional vs. object-oriented programming. You probably can achieve the same thing with both of the approaches. In JavaScript, it is even easier, you have both of the approaches available. Libraries like lodash give you a really nice collection of tools for building applications with a functional approach. Nowadays, it is not even necessary to use external libraries any more. A lot of the most important functions have been implemented in the official JavaScript specification. You definitely should know how to use map `reduce` filter `forEach` and `find`.

8. Object Oriented Approach

Similar to the functional approach, you also have to get familiar with object oriented JavaScript, if you want to master it. I neglected that part for a long time in my career and just worked my way through with a workaround, but sometimes it is definitely better to use objects/classes and instances to implement specific functionality. Classes are widely used in React, MobX or custom constructors.

9. Frontend Framework

The big three are React.js, Angular and Vue.js. If you are looking for a job nowadays, you will almost always have one of those listed as a prerequisite. Even if they change quite quickly, it is important to grasp the general concept of those to understand how applications work. Also, it is just easier to write apps that way. If you haven’t decided which train you want to jump on, my suggestions is React.js. I have been working with it for the last couple of years and did not regret my decision.

10. Bundling / Transpilation

Unfortunately, this is a big part of web development. On the one hand I should not say unfortunate, because it is great to be able to write code with all the newest features. On the other hand, the reason why I’m saying that is that we always have to keep in mind that there’s older browsers around that may not support these features, therefore we have to transpile our code into something else that the old browsers understand. If you work with node.js, you will probably have less exposure to transpiling your code. The de-facto standard for transpilation is babel.js, so get familiar with it. As for bundling your code and tying everything together, you have a couple of options. Webpack was the dominant player for a long time. Some time ago, parcelpopped up out of nowhere and is now my preferred solution, since it is so performant and easy to configure, although not perfect.

10 Popular JavaScript Frameworks for 2019

JavaScript is growing fast, it’s becoming more native, but most importantly — it’s becoming more stable. The number of web development frameworks that have come into the JavaScript sphere in the last years has really boomed. Many of the frameworks have already established huge communities around them, Angular, Meteor and React to name a few. In today’s post we will be taking a closer look at the currently most popular JavaScript frameworks. We strongly believe that these frameworks will be seeing a lot of growth, engagement, and exposure. Please share with us your personal experiences with the frameworks that you have used from our list as we would love to hear more input about the use cases for each individual framework.

When it comes to Web Development, JavaScript frameworks are one of the most favored platforms for developers & businesses in today’s time. Possibly, you have had a chance to experiment with one or two of the popular JavaScript Frameworks too. However, somewhere in your mind, you are still a little unsure about the best one to devote yourself to mastering or suggest your developer to opt for your next web development project.

This is quite obvious. JavaScript is moving at a breakneck pace and there is constant pressure to add new skills to your repository. In order to do that, knowing and understanding more of the top JavaScript Frameworks in today’s time is necessary. After thorough voting by 300+ developers at Simpliv, we shortlisted a few of them and here they are:

 

These are the top 10 JavaScript frameworks that we like. Which one is your favorite? Any exceptional JS framework that we missed?

Choosing the Best JavaScript Development Framework

Choosing a framework should never be about the number of features that the particular framework can provide. Terms like ‘next generation’ can sound very appealing, but what matters is the actual functionality of the framework. The usage of functionality within your own new project, app, and software can also be a factor. Some frameworks provide more experience by letting sensational developers with decades of experience build the framework. Whereas, smaller web frameworks will focus on community-oriented features that it can incorporate within different framework modules.

How to Become a Great JavaScript Specialist | How to Practice Javascript

Javascript has become the most import language you can learn.

Years ago, you could produce a web site with HTML alone. Now, Javascript is a critical technology that makes not just interactive web sites, but full web applications. Modern sites don’t just display data but generally help users complete tasks such as making a reservation or buy an item.

Javascript is a critical part of these transactions. Handling everything from dynamic screen content to interacting with remote servers, every developer needs Javascript.

And, Javascript is not just a web language any more. Due to related technologies like Node and Phone Gap Javascript can now be used in web development (client and server side) and mobile development.

This is only part of the reason that Javascript is THE language to know.
