Q: I want to code with JavaScript, do I need to download a JavaScript installer to my computer?
A: You can run JavaScript in your browser, there is no need to download and install JavaScript on your computer. Just press F12 on your keyboard to open the developer console. Then you can enter your JavaScript code and execute it directly in your browser.
There are also online environments where you can execute JavaScript directly in your browser without opening the developer console.
For example jsfiddle.net or codepen.io.
The NodeJS is another good option for learning and creating JavaScript code for network applications. It is powered by Chrome's V8 JavaScript engine.
You can get the Node.js from nodejs.org.
If you want to create cross-platform desktop applications with JavaScript then check the ElectronJS. It is built on the NodeJS engine.
You can get the ElectronJS from electronjs.org.
