title: TSLint on javascript files
body: <p>I spent many hour getting this to work, still without success...</p>
  
  <p><strong>The question is: How to use the TSLint on .js file?</strong></p>
  
  <p>Why? I'm trying to have best possible IDE for writing many JavaScript scripts, used in our internal SW.</p>
  
  <p>My vision:</p>
  
  <ul>
  <li>I have well documented TypeScript definitions of functions and want to use them in .js.</li>
  <li>I want to import .js file and see the errors on it. TSLint is capable to do type control on .ts, according to .d.ts files. But on .js file, JSHint/ESLint can only see the function names and parametres from .d.ts files. Ok, but it's not enough. There is no type control in .js, which I'm missing.</li>
  <li>Use JSHint/ESLint with TSLint in the same time. Using only few functions from both, but making great combo in the end. (TSLint for types, JSHint/ESLint for the rest)</li>
  <li>Do not allow to use TypeScript keywords in JavaScript.</li>
  <li>Autocomplete in .js from .d.ts. Ok, this is working.</li>
  </ul>
  
  <p>I can code in VSCode, Sublime, NetBeans.</p>
  
  <p>Thank you for an ideas!</p>
