The author of this article is tech expert Pieter Murphy.

Many people aspire to follow the JavaScript career path to achieve professional success, and with good reason. JavaScript is a widely used and highly popular programming language, so there are mountains of legacy code. Plus, it’s a versatile option, which helps keep it relevant for new projects.

Fortunately, the JavaScript developer roadmap is reasonably straightforward. If you’re hoping to launch a new career or pivot in an existing one, here’s a look at the Java Script roadmap for the aspiring developer.

The Role of JavaScript in Web Development

Before going over the learning JavaScript roadmap, it’s critical to understand a bit about what the programming language entails and how it applies to web development.

JavaScript is a scripting language most commonly associated with frontend development, but it can play a crucial role in backend development as well. Here’s a quick overview of how it’s used in each of those cases.


For the aspiring front-end developer, knowing JavaScript is a boon. It allows app development professionals to create user interfaces and make platforms interactive. It’s also suitable to ensure applications render correctly when using an array of web browsers.

While native apps written in JavaScript won’t run on mobile devices, that doesn’t mean JavaScript can’t play a role in mobile application development, too. However, there are tools like PhoneGap that make it possible, so keep that in mind.


JavaScript is less common in back-end development, but that doesn’t mean it has no value in this area. Node.js is a runtime environment that allows JavaScript code to play a role in server-side operations. Primarily, it supports database interactions, allowing the client-side aspect of the application to display the right data based on user input provided through web applications. 

Additionally, JavaScript can play its part in the worlds of cybersecurity and data storage. It helps ensure that information is managed correctly and that connect systems are safeguarded from threats.

Steps to Learn JavaScript

If you want to become a JavaScript engineer, there’s a reasonably straightforward JS learning roadmap that can get you to that goal. Here’s a look at the steps you’ll want to follow to learn this fantastic programming language.

JavaScript roadmap 5 steps

Step 1. Learn the Basics of JavaScript

The beginning of the learn JavaScript roadmap focuses on the basics, as those give you the strongest possible foundation. Usually, you want to learn specific fundamentals, including information about classes, data types, variables, operators, functions, objects, and loops.

Usually, you’ll want to focus on syntax at this stage of your learning journey, as well as study methods. Diving into control flow and DOM node is similarly helpful.

Precisely how you go about learning the basics is less important than taking in the information. You can choose an approach that works best with your learning style. Just make sure to use some practical application for experience, as that can speed up the learning process.

Step 2. Learn Advanced JavaScript

After getting the basics down, the next step on the roadmap for a JavaScript developer is to move on to more advanced operations, features, and functions. Promises and callbacks are both worth learning. Additionally, you’ll want to familiarize yourself with error handling, async-await, data structures, modules, and OOP. Getting comfortable with asynchronous code is another wise move at this stage.

There are other areas you can check out, too. Scopes, closures, arrow functions, and IIFEs are worth diving into at this point. As with the previous step, doing some practical exercises is an intelligent idea, as it helps you gain hands-on experience.

Step 3. Learn JavaScript Frameworks and Libraries

Once you’re comfortable with JavaScript, it’s time to dive into JavaScript frameworks and libraries. For frameworks, popular options are Node.js, jQuery, Vue.js, and Angular. However, there are many others that provide substantial value, so feel free to broaden your horizons.

For the best JavaScript roadmap, library options are also part of the equation. React and Redux are both prime examples of widely used libraries, so they can serve as a solid starting point.


Reach uses JavaScript – along with HTML/CSS – to create user interfaces for various React applications. It relies on a DOM to render browser code, unlike React Native, which uses Native API for component rendering in mobile applications.


Angular is a JavaScript framework written in TypeScript. It’s primarily used for single-page applications, allowing developers to harness a standard structure for their projects. It also features a collection of libraries, which can accelerate development.


Vue is a framework that assists with building user interfaces, so it’s primarily used for frontend development. It offers a component-based and declarative programming model that increases efficiency by reducing complexity.


jQuery is a JS library that simplifies creating websites with JavaScript. It’s a highly feature-rich option that reduces the amount of manual coding required when building dynamic web applications.

JavaScript Frameworks Comparison Table

When you’re looking at essential technologies that support your developer career, determining which frameworks best suit various situations is challenging. To make the process easier, here’s a quick comparison table of two of the most popular options.

Angular vs VueJs

The Rise of Server-side JavaScript with Node.js 

While developers focused on the front-end may not need Node.js, it plays a big role in server-side JS back-end development. It integrates a variety of frameworks and libraries to support server-side web applications, and it’s particularly helpful for data-intensive apps since it relies on an event-driven and asynchronous model.

Node.js can read, write, create, open, close, and delete server files. Plus, it can collect data from forms, modify, add, or delete database data, and generate dynamic page content. Ultimately, it’s highly versatile, which has caused its quick rise in popularity.

Step 4. Learn ECMAScript Standards

After handling the steps above, the next phase of the roadmap to learn JavaScript involves focusing on ECMAScript. It’s a JavaScript-based scripting language standard. Essentially, it defines what a scripting language should look like, creating an inherent sense of consistency. It’s a specification upon which JavaScript is based, so understanding it can provide ample value.

Step 5. Learn JavaScript Development Tools

Another critical part of the JS developer learning path is studying various development tools. Precisely which ones provide value may vary depending on the precise direction of your career. However, some are always worth learning, making them excellent starting points. Here are a few tools you’ll want to familiarize yourself with to ensure you’re ready for a JavaScript career.


Integrated development environments (IDEs) are software tools that help developers write, test, and debug code. Each IDE has a variety of features to cover all of those bases, which can simplify development dramatically. Some of the most popular options include Visual Studio Code, WebStorm, Sublime Text, Light Table, and Brackets.

JavaScript Package Managers 

Package management software – also known simply as package managers – provides methods for installing new dependencies. They can find, download, install, configure, upgrade, and remove packages, as well, making it easier to ensure the right ones are in place when working on projects.

There are several popular JavaScript package managers currently. One of the most widely used is Node Package Manager (NPM). Yarn and pnpm are also widely used.

Debugging and Testing Tools

Whether you’re focused on back-end or front-end development, having the right debugging and testing tools is essential. They allow you to validate your code to ensure it runs properly and identify errors that could cause issues as your project moves forward.

There are many JavaScript debugging and testing tools that provide excellent value. For debugging, some popular options include JS Bin, Airbrake, Firefox JavaScript Debugger, ESLint, Raygun, and Rollbar. In the world of testing, options like Jest, Selenium, and TestComplete.

Future of JavaScript

JavaScript is still an in-demand skill, both for back-end and front-end developers. It’s a popular programming language with developers, and there is a substantial amount of legacy code. That means JavaScript is destined to remain relevant for the foreseeable future.

One reason JavaScript is still worth knowing is that its use is expanding. While developers using it were initially focused on web development, server-side applications are continuing to grow. Its ability to support users without overburdening servers is also why JS is highly popular, as it allows for smooth and engaging applications without overusing internal resources.

Something intriguing is the increasing focus on enhancing JavaScript security. In an era when cyber threats are at the top of many people’s minds, finding new ways to protect JavaScript applications only enhances the language’s value.
