js code completion

[Potato232]

Hello, let’s say I am a beginner programmer and want to use javascript for development. I met a problem, namely auto code completion. As I know in visual studio 2019 (for c #), you can implement this, but I did not succeed in doing code completion in visual studio code (for example) for js. As I did not try, I searched for a long time, found something related to it (npm packages, but I do not understand them).

I ask for help, thank you in advance
