How to become a JavaScript Developer – Top 10 tips

During this current era of technology, it’s comparatively hard to choose which technology you are going with, especially when it comes to programming, you need to filter out your interests and get into the programming world by choosing a specific programming tool/language which will help you to pursue your interests.

Technology has advanced in the modern world, making life simpler for both users and developers. JavaScript is a very handy tool when it comes to creating modern world applications (Single page Application/ Single-Threaded Applications). The race of learning modern JavaScript is growing up day by day hence you need to adopt the best ways to become a professional and efficient JavaScript Developer.

This article will help you to decide the best road map to become a professional JavaScript Developer.

Introduction to JavaScript?

JavaScript is a text-based computer language that can be used to create both client and server-side interactive web pages. While HTML and CSS provide web sites structure and style, JavaScript adds interactivity that keeps people engaged.

If we take a look at the tools and technologies used in the past 10-15 years, because of having a multi-page web structure, it was causing a heavy load on the server as it reloaded complete information of the webpage whenever a server call was generated. Hence it was causing the webpage to be very time-consuming and resource hungry. But finally, there came a concept of Manipulating DOM (Document Object Model) which allowed us to keep all the data into the browser’s local storage once it got loaded from the server for the first time. And later on, whenever we needed any content update on the page we just needed to manipulate the DOM to modify the specific content without reloading the whole page.

This concept was very useful and hence we finally got JavaScript to handle this process using its handy features to make our life easier. So now, the entire web is transforming into JavaScript-based technology.

There are many JavaScript frameworks available in the market like React.js, AngularJS, Vue.js. Now the point here is how to learn these latest technologies faster.

This article will allow you to decide the best road map and tips for learning JavaScript and you will learn how to become a full-stack JavaScript Developer.
Let’s dive into it.

Learning fundamentals of JavaScript

Like other languages, C, C#, C++, and Java, JavaScript has the fundamentals on which it is based. Basically, the fundamentals are the rules and methods on which a particular language is based on. No doubt you can’t learn full-stack web development as a matter of fact without learning JavaScript itself, yes you don’t need to be a master to get started with JavaScript, but you should have a basic understanding of JavaScript paradigms. Contrary to other technologies, JavaScript is not a very hard language to learn.

It may look sloppy at the beginning but when it is used in a correct way, it is very handy and can do everything you want it to do. Objects and primitives are the two kinds of data in JavaScript whereas boolean, number, string, Null, and undefined are the five primitives.

In JavaScript, everything else would be an object. JavaScript itself has evolved so much as at the beginning it was a simple language then vanilla features were added into it, that ES6 and ES7 came in and made our life easier by providing us with more reliable and shorthand functions. JQuery and Ajax introduced the concept of Asynchronous programming.

Use Object-Oriented Approach

The object-oriented method is the most well-known programming approach today. Since its inception with C++, the object-oriented paradigm has exploded in popularity. Today, only object-oriented programming is used to create all of the main languages. An object-oriented strategy is one that is focused on a specific object. The object then becomes a fundamental entity. This object is then used to add attributes and functions to the page as a basis.

Understanding DOM

When a page is loaded into a browser, the DOM (Document Object Model) is formed. This includes a number of levels that make it simple to access the various parts. With so many front-end frameworks and jQuery’s widespread usage, you would think that knowing the DOM is no longer necessary. On the contrary, I believe that understanding how the DOM works is critical to becoming a JavaScript master. JavaScript has the ability to modify any HTML element. It has the ability to alter your background color, font, and anything else. Knowing what will influence what is essential when JavaScript has enough power and is employed so widely inside HTML. As a programmer, you should understand how altering child and parent properties at the same time affects the page’s overall structure. For a JavaScript developer, the DOM is one of the most fundamental and crucial concepts, and he/she should be well-versed in it.

Shifting on Frontend Frameworks

There are many frontend frameworks in JavaScript but the most popular ones are AngularJS, ReactJS, and VueJS. Due to speed advantages, one-page apps are the way to go nowadays. Learning a front-end framework is the most practical way to create one. The most popular are Angular, React, and Vue, although they aren’t the only ones. In the JavaScript world, there’s a race. If you Google “Angular versus React,” you’ll find a slew of articles comparing the benefits and drawbacks of each. Because of the given reasons, I prefer Angular. In some cases, React or Vue might be a nice option.

Learn CSS frameworks for Stylings (Bootstrap 4)

You won’t have time to create all the necessary CSS code yourself to make your web app look nice whether it’s viewed on a regular desktop or a mobile device nowadays when virtually all web apps must look nice whether they’re accessed on a regular desktop or a mobile device. Many elements in front-end web development, such as popovers, pop-ups, navigation bars, notifications, and so on, may improve the user experience. If you try to add these features on your own, you’ll end up with a huge amount of boilerplate code that will take forever to create and maintain.

Learning Backend Frameworks (Node.js, Express)

NodeJS is a programming environment that allows you to run JavaScript on the backend like any other programming language. There will, of course, be some small distinctions between JavaScript on the desktop and JavaScript on the browser. The V8 engine is used by both the browser and Node to execute JavaScript. The main distinction is that the browser offers an extra API for accessing the DOM, whereas Node adds an API for interacting with the operating system. You’ll need to know NodeJS if you want to do full-stack JavaScript. The nice thing is that you do not need to learn a new language from scratch.

Express is then a complete framework that allows a rapid development process and makes life easier as it provides a complete backend utility where we don’t have to write the server-side code by ourselves as it provides on its own.

Learning Typescript

JavaScript itself has uncountable issues in it such as.TypeScript generates ES5 code, which eliminates many of the compatibility concerns.

I’ve enhanced my programming abilities and gained a better understanding of topics like interfaces, inheritance, access control (public, private, etc.), and abstraction by using TypeScript. If you come from an OO background, as I do, TypeScript will seem far more natural than plain JavaScript. Another advantage of TypeScript is that it may be used with a lint file to enforce code standards.

Get your hands on MongoDB or any Relational DB

MongoDB is cross-platform document-oriented database software that is open source. MongoDB is a database developed by MongoDB Inc. and provided under the terms of the Server Side Public License.

Traditional RDBs are replaced by NoSQL databases. Working with huge quantities of dispersed data is a breeze with NoSQL databases. MongoDB is a database management system that can store and retrieve document-oriented data.

Using MongoDB along with Express makes the workflow speedy and more secure than a traditional node.js Applications

Practice SQL

SQL (Structured Query Language) is a very handy tool that helps you to interact with relational databases. SQL is a powerful language that helps you to send and retrieve data from databases like Mysql, OracleDB, and PostgreSQL, etc. This will be another important paradigm of learning full-stack development as this will be frequently used in applications as this is the only tool that will help you to connect your running application with the database to send and retrieve data.

Make your practices regularly

Accept as many problems as possible in addition to finding answers and creating websites. Challenges can take many forms, such as imagining a highly complicated feature on a website for practice. This will assist you in learning JavaScript at a higher level than others. You may need to learn a new library, a new idea, or both for that one feature, but it will undoubtedly benefit you in the future. So, constantly strive to come up with complicated ideas, and you’ll learn a lot more than you think.


So, being a JavaScript developer is simple, becoming a JavaScript master is a little more challenging. It allows you to notice gorgeous components that do things you never dreamed of. The principles I mentioned above are crucial in becoming a JavaScript expert. Keep these in mind and implement them one by one. You are ready to compete with anyone and build anything (imagined or not) in the internet world once you have fulfilled the goals stated in each chapter.
