You may have taken the time to learn JavaScript after learning how to use HTML and CSS for web development, as it is a popular front end web development language. JavaScript is a programming language that enables individuals to add interactivity to websites, including building mobile and web applications. 

If you’re well-versed in this programming language, you may be ready to move on to something more challenging. Fortunately, learning JavaScript opens up numerous other doors in the world of programming. For example, you might choose to learn how to use a JavaScript library (or two). Or maybe you take your JavaScript “behind the scenes” to work server-side with tools like Node.js or MongoDB. 

Below are a few examples of tools to learn after JavaScript. In this article, you will also find suggestions for where and how you might learn these tools, including self-study, formal education, and online or in-person classes. 


A great way to add to your JavaScript toolset is by learning JavaScript-specific libraries and frameworks. React is an open-source JavaScript library that individuals can use to build user interfaces. This library is maintained by Meta. 

React is made up of blocks of code called components, which can then be used again and again. In other words, web developers can quickly apply pieces of code to various projects, making their web development move more smoothly. 

How to Learn React

JavaScript Development Certificate: Live & Hands-on, In NYC or Online, 0% Financing, 1-on-1 Mentoring, Free Retake, Job Prep. Named a Top Bootcamp by Forbes, Fortune, & Time Out. Noble Desktop. Learn More.

Because React is an open-source tool, some may choose to learn how to use this library through self-study. This can be a good way to learn if you have already successfully taught yourself another programming language or tool. Alternatively, you may consider enrolling in a more structured course, such as online or in-person courses offered through Noble Desktop. 

Noble’s React Development Bootcamp teaches individuals how to build dynamic web applications. This includes learning how to build basic components, which form the underlying structure for React. To participate in this course, individuals should be comfortable using JavaScript, as well as know the basics of HTML and CSS. 

Back End Programming with Node, Express, and MongoDB

One of the great benefits of JavaScript is that it can be used both on the front end and back end of a website. Certain tools, such as Node, Express, and MongoDB are compatible with JavaScript and allow programmers to work server-side with this language. 

Node is a runtime environment that enables JavaScript to run server side. In other words, Node enables developers to code on the backend with JavaScript. Another related tool is Express.js, a Node web framework that allows developers to quickly create web applications and servers. Finally, MongoDB is an open-source tool used to help organize, store, and manage data. 

How to Learn Node, Express, or MongoDB

If you’ve already learned how to use JavaScript, you can begin familiarizing yourself with tools like Node, Express, or MongoDB. Many people choose to learn how to use these tools through self-study. 

Alternatively, you may prefer a structured learning environment where you can ask instructors questions and receive individualized support and feedback. Noble Desktop offers virtual and onsite classes at its Manhattan campus, including a JavaScript Development with Node, Express, and MongoDB course. In this 72-hour class, students learn how to use each of these tools. Before enrolling in this course, students should be comfortable using JavaScript. 


Of course, you also can’t go wrong by increasing the number of programming languages you know how to use. Because it uses a simple syntax, many programmers find learning Python very intuitive, especially those who already have previous experience coding. 

Python is an excellent choice for those who would like to learn more about building server-side web applications. This language is incredibly versatile and developers can also use Python for purposes like data analysis, machine learning, and automation. 

How to Learn Python 

Because Python is an open-source programming language with a relatively straightforward syntax, many people learn how to code with it through self-study. Additionally, you may be able to learn how to use Python while enrolled in a college or university’s Computer Science degree program. 

But don’t despair if neither of those options sounds like they would work for you. Noble Desktop also offers virtual and in-person classes that cover Python. Its Python Developer Certificate helps prepare individuals for roles like Back End Developer, Python Developer, and Software Engineer. In addition to gaining a foundation in coding with Python, this course also covers how to work with APIs, SQL, and Django, among other tools.


JavaScript serves as an excellent foundation for anyone who wants to build websites and applications. This includes those who would like to pursue roles as Web Developers. By learning tools like React, MongoDB, and Express, individuals can apply their skills to a wide array of purposes in the field of web development. 

If you’d like to learn all of the tools listed above, you may also consider enrolling in Noble’s Full Stack Web Development Certificate. This course prepares individuals for roles as Full Stack Developers, including learning both front end and back end development. In particular, students learn how to use HTML, CSS, JavaScript., React.js, node.js, MongoDB, and Express.js, among other tools.
