title: How to run typescript-eslint on .ts files and eslint on .js files in the same project in VSCode
body: <p>I have a mixed codebase with javascript and typescript files. I'd like to have eslint run on .js files and typescript-eslint run on .ts files in VSCode.</p>
  
  <p>I've managed to configure my .eslintrc.json file to get typescript-eslint to run on .ts files. The problem is that it also ends up running typescript-eslint on .js files, instead of plain old eslint.</p>
  
  <p>This seems like it should be simple and fairly common, but I haven't been able to find a solution despite searching all over the internet.</p>
