What is, in your opinion, the best web development IDE when you work with Html, Css and Js?

Answer 1

visual studio code - which is free:
https://code.visualstudio.com/download

webstorm - which is paid but you have 30 days free trial:
https://www.jetbrains.com/webstorm/download/

i use webstorm and it helps a lot with the debugger. it allows you to debug like a normal IDE would, with breakpoints and such.
you also have support for Angular, React.js, React native, Vue.js
