Top 10 best Javascript Certifications [updated 2021]

A JavaScript certification can work as evidence to a potential hiring manager that all concepts about this programming language are known and dominated.

But before we go further, it's important to say that a certificate alone will not land you a job. Experience also counts, no matter if you're a junior or a senior developer.

A Javascript certification can work as a milestone in learning. Or even present you to a new world of possibilities.

Are you prepared to know the best certifications to become a certified Javascript Developer?

Get on board!

What is the use of JavaScript?

You can learn a lot with a Javascript certification, but given the intimate relationship between Javascript and the web world, you might need to know some HTML and CSS.

HTML allows developers to create an essential structure for a page's text. CSS allows us to apply styling to a page. And Javascript has historically been the bridge with which you could add some sort of dynamism to a page.

This dynamism has grown disproportionately bigger in importance than the other two in recent years, to a point where the language alone can be used to create and style a web page. But don't be afraid to go on just because you don't know CSS and HTML yet. A lot of certifications include CSS and HTML lessons.

As you start delving further into Javascript, you will learn about frameworks and libraries, which are very important for building brilliant user-interfaces.

You will also learn how to create web servers, APIs, and connect the frontend with the backend.

How do you become a certified Javascript developer?

The easiest way to become a certified Javascript developer is by enrolling in online certifications provided by e-learning platforms such as Treehouse, Udacity, PluralSight, Udemy, and more.

Is JavaScript hard to learn?

This is the question every beginner asks. The answer is simple. No, JavaScript is not hard to learn.

But definitely, it is challenging to master. Learning its basics is not a tough challenge, although when you gradually move to the intermediate and advanced topics, it starts to become challenging.

If you have experience in other high-level programming languages such as Java, then starting with JavaScript is not going to be a big deal. Much of the syntax of JavaScript is similar to Java, and C++.

The basics won't take much time; JavaScript's syntax is more natural to catch when compared to most programming languages.

If you are a beginner, you need proper guidance. Starting JavaScript without any guidance will only make the journey harder.

There are several ways to have guidance, such as online courses and certifications. It is strict advice never to skip any concept. Always go with the flow.

The journey can be tough in the starting, especially when you are trying to understand syntax. Try to practice as much as you can.

HTML vs JavaScript

HTML is a markup language, while JavaScript is a scripting language. There is a lot of difference between both of them.

HTML stands for HyperText Markup Language. It has several elements that are used to create an essential structure for web pages. These HTML elements, also known as HTML tags, are written using angular brackets.

For example, to write a paragraph, <p> tag is used. It has a corresponding closing tag </p>.

A few tags such as the <img> tag used for adding images do not have a similar closing tag. HTML is used to create a static web page.

It is a basic structure which only displays whatever is hardcoded.

On the other hand, JavaScript is a high-level programming language that is used to convert a static HTML web page into a dynamic one.

For example, we can create a button using HTML's <button> tag. But to make something happen when it is clicked, we need JavaScript.

HTML is simple to learn and does not take long to understand how its elements work. HTML is limited, as a markup language it is utilized to create the basic structure of a web page.

On the other hand, JavaScript brings infinite possibilities, and it requires effort and time to learn. When compared to HTML, JavaScript is challenging to learn and understand.

If your aim to become a Web developer, then both HTML and JavaScript are requirements. However, JavaScript does not have any relation or dependency on HTML. So if you wish to become a JavaScript developer, you can directly start with JavaScript, but to become a web developer, you'll also need HTML.

Java vs JavaScript

Java and JavaScript are not the same, not at all. Java can be more difficult to learn than JavaScript. These two programming languages emerged in the mid-90s.

At that time, Java was a dense programming language for professional developers, while JavaScript was created as a light scripting language.

So this is why both of these languages have similarities in name and syntax. The syntax of Java can be complex, and it takes time to get familiar with it. Moreover, Java is not that programmer-friendly.

On the other hand, the syntax of JavaScript is easy to catch, and it is more programmer-friendly than most of the different programming languages.

Quick tip: once you understand the syntax of JavaScript or Java, both will get easier over time.

Both of these languages are widely used, mostly in web and mobile application development. Java is also a big name in desktop GUI application, enterprise application, scientific application, gaming application, and cloud-based application.

So Java is used more widely than JavaScript. But JavaScript is the top name in web application development, and it is also gaining popularity in cross-platform mobile application development.

Python vs JavaScript

Apart from Java, Python is another programming language whose usage can challenge the popularity of JavaScript. Syntax-wise, both JavaScript and Python are very programmer-friendly.

But generally, the syntax of Python is considered most comfortable among all other programming languages. So learning and understanding Python is easier on the beginner level.

Python is also a prominent name in the web development community.

However, the popularity and usage of JavaScript are still higher than Python. Python is also popular in other domains such as game development, machine learning, artificial intelligence, desktop GUI, web scraping, and embedded application.

jQuery vs JavaScript

jQuery is a library that is combined with JavaScript. The main focus of jQuery is DOM manipulation. It is crucial to understand DOM and its working to create dynamic web pages. As working with DOM can be complicated, jQuery is used to simplify it.

jQuery is used for DOM tree transversal for example. It is also utilized for event handling and animations. Moreover, it is commonly used with AJAX. The syntax of jQuery in a way to navigate easily through the DOM tree. The selection of DOM elements becomes easy with jQuery. It is also combined with CSS.

It is one of the most widely used libraries with JavaScript. The syntax can be confusing initially, but once the basics are clear, it is easy to use jQuery with JavaScript.

How long does it take to learn JavaScript?

As mentioned earlier, JavaScript is a vast language. So learning it will take time as well as effort.

The journey is a bit long, but it is worth it. For a beginner, the very first challenge is understanding the syntax. It will take time to learn the syntax and understand how to use it.

This stage should be given proper time and effort because the next steps depend on it only. The basics of programming, such as statements, loops, and conditions, are mandatory to understand.

Understanding the basics will ease the journey.

The intermediate and advanced level concepts, such as functions and objects are also mandatory. Most beginners usually go through these concepts and move forward without practice.

This is a mistake.

Give time and effort, and try to go as deep as you can. It will not only clear your concepts but also help you in job interviews, because most of the questions in JavaScript job interviews come from these intermediate and advanced level concepts.

The same journey for an experienced programmer is short and easy. JavaScript's syntax is similar to Java and many other programming languages.

So the syntax and primary will not take much time, and you can move on to the advanced concepts in a short time.

JavaScript jobs: Is JS enough to get a job?

As mentioned earlier, JavaScript is one of the most popular languages, and in some surveys, it is the most popular programming language in the world.

So if you are well-trained in JavaScript and understand the working of the language, you may find a decent job.

There is so much that could be done with JavaScript, such as client-side development and server-side development.

Companies usually desire a developer with expertise in JavaScript frameworks and libraries such as Angular and React, or in the backend technologies such as Node.js.

But many companies also prefer to hire developers who are skilled in JavaScript, so that they can use their skills according to their requirements, or the companies can train the developers in the required technology.

What jobs can you get if you learn JavaScript?

If your basics are clear and you understand concepts such as objects, ES6, and other advanced level concepts, you can find a job as a JavaScript developer.

Along with JavaScript, HTML and CSS are two other core technologies of the World Wide Web. So learning HTML and CSS will help you evolve in this field.

There are several job domains for a JavaScript developer. One of the significant fields is the User-Interface developer.

JavaScript frameworks and libraries such as Angular, React, and Vue are in high demand, and if you are familiar with these, then your chances of finding a job increase considerably.

But to learn such frameworks and libraries, you must understand JavaScript properly.

What else should you learn to become a web developer?

Apart from JavaScript, HTML and CSS are mandatory to become a web developer. Moreover, in modern web development, you also need frameworks and libraries such as Angular and React.

For those who want to be frontend developers:

The part of a web application that is visible to the user is called the front-end. A basic, simple front-end can be developed using HTML, CSS, and JavaScript. If you want a high performing, more interactive front-end, you will need additional JavaScript frameworks and libraries.

HTML

HTML is a markup language that is utilized to create the basic structure of a web page. It consists of several HTML elements, each having its attributes.

HTML is used to create a basic structure of a web page. Further, CSS and JavaScript are applied to an HTML document.

When compared with JavaScript, HTML is easy to understand and learn.

It does not take much time to understand HTML tags and attributes. If you want to learn HTML, you can go for the following course.

CSS

HTML only creates a basic structure which is not appealing. CSS is utilized to make a website more attractive.

Several CSS properties are used to convert a boring HTML page into an attractive one.

No website today is complete without CSS. The presentation of a website is as important as its features. A front-end developer must understand the working of CSS and how it is applied to an HTML document.

Like HTML, CSS also does not take much time to learn and understand. But it is vast. There are several concepts, properties, and ways of using CSS, not only through HTML but also through JavaScript.

If you want to learn CSS, you can try this course.

JavaScript´s Framework: React and Angular

Angular

It is already mentioned several times in this article that HTML, CSS, and JavaScript alone are not sufficient to create a modern web application. You will need additional frameworks and libraries.

Angular is one of the most popular and widely used JavaScript frameworks. It is a full-fledged framework that has almost everything that is required to create a dynamic web application.

Angular is full of concepts. There are many concepts as directives, components, injections, and others. It is fair to say learning angular can take time and effort, but it is worth learning because there are many job opportunities for angular developers.

React

React has emerged significantly in recent years. It is one of the most popular JavaScript libraries that is overgrowing because of its high performance.

The main aim of using react is UI rendering. Instead of real DOM, React uses virtual DOM, a lightweight copy of the real DOM. The usage of virtual DOM considerably increases the performance of the application.

As React mainly focuses on UI rendering, it requires additional libraries for other features such as state management. There are several courses available online. If you want to learn React, you can try this course .

This course also covers additional concepts such as redux and react hooks, which are very useful while working with React.

For those who want to be backend developers

The backed part is responsible for the dynamic behavior of a web application. The database is one of the critical elements of the backend. Generally, every web application has a database connection that stores the data displayed on the front-end.

Node

Initially, JavaScript can only be used inside the JavaScript. So it was limited for client-side use only. But with the emergence of Node, it became possible to use it outside the browser.

In the past few years, Node has become a big name in server-side development. It is used with several different types of databases, such as SQL, and MongoDB.

Node is one of the technologies used in MEAN and MERN full-stack development. If you want to learn Node you can try this course .
