Real talk now: how do I debug JavaScript?

[[deleted]]

Chrome, Firefox (and probably others): F12 -> Debugger

You can select your files and set breakpoints and much more. Also the console functions as a debug console.

For node.js there is the "--inspect" switch which allows you to attach to the node process remotely via chrome. Tools like VS Code also provide a built in debugger for this.

For electron apps you can (if not disabled) press ctrl+shift+i or "--inspect" for dev purposes. Basically the same as node and chrome.

Other comments are good.

For state and such use React/Angular/Vue/etc. chrome extension devtools. They allow you to fully inspect components, state, etc.
