Best Free and Open Source JavaScript Runtime Environments

Last Updated on May 24, 2022

The JavaScript runtime environment provides your scripts with utility libraries which can be used during execution. It’s your script that references these libraries. The engine itself doesn’t depend on them.

Unlike C and other compiled languages, JavaScript runs in a container. A program reads the JavaScript code and executes it. This program needs to parse the code and convert it into runnable commands. It must also provide objects to JavaScript so that it can interact with other things. The first part is known as the engine, the second is the runtime.

The runtime environment takes on different forms depending on the context. For example, the runtime environment in a web browser is different from that of Node.js. In a web browser, the runtime is comprised of the JavaScript engine, web APIs, the callback queue, and the event loop.

Here are the best free JavaScript runtimes. Here’s our verdict. We feature only free and open source software here.
