A simple language server for JavaScript, powered by ESLint and Tern.

I made this because sourcegraph/javascript-typescript-langserver is really bad at untyped JavaScript. It uses the intellisense library that's part of TypeScript as a backend, which makes it really good at TypeScript (probably, I've never used it for TypeScript) but much worse than Tern at regular JavaScript.

# Using the thing

I'm a vim user, so I just do this:

```

let g:LanguageClient_serverCommands = {

    \ 'javascript.jsx': ['js-langserver', '--stdio'],

    \ }

```

If you want to use VSCode, I think you're going to have to fork the project and add a 20-line VSCode extension. Not really sure how VSCode works.

VSCode's builtin JavaScript support is not in here because I can't figure out how to use it with vim. vscode-ternjs is here despite having 1 GitHub star because it is literally the only language server I could find that used Tern.
