Quickstart JSLint in Vim

Download and save jslint.mjs, jslint_wrapper_vim.vim to directory ~/.vim/
Add vim-command :source ~/.vim/jslint_wrapper_vim.vim to file ~/.vimrc
- If above files were saved to custom-directory, then use that directory instead, e.g.:
  - save jslint.mjs, jslint_wrapper_vim.vim to directory ~/vimfiles/
  - vim-command :source ~/vimfiles/jslint_wrapper_vim.vim
Vim can now jslint files (via nodejs):
- with vim-command :SaveAndJslint
- with vim-key-combo <Ctrl-S> <Ctrl-J>

screenshot

Quickstart JSLint in VSCode

In VSCode, search and install extension vscode-jslint
In VSCode, while editing a javascript file:
- right-click context-menu and select [JSLint - Lint File]
- or use key-binding [Ctrl + Shift + J], [L]
- or use key-binding [ Cmd + Shift + J], [L] for Mac

Documentation

jslint.mjs contains the jslint function. It parses and analyzes a source file, returning an object with information about the file. It can also take an object that sets options.
index.html runs the jslint.mjs function in a web page.
