If you want to install JavaScript in VSCode, install Visual Studio Code & Node.JS, create and run a JavaScript program, and then take these steps.

Beyond the flexibility of being able to code from anywhere, VSCode.dev can turn any cloud machine into a development platform, and give you full-blown IDE interaction with your projects on the cloud.

You now have your own functional development container! VSCode will automatically start the container when you open your project and close it when you close Code or switch to another project.
