Using JSLint
  • Right click on a project in the left-side project view
  • Select enable jslint4java
  • Select Project -> Clean
  • View updated results in Problems view on bottom
    • If not visible, Window -> Show View -> Problems
  • View results in any JavaScript file while editing and clicking on yellow markers on right

To better support progressive enhancement and working with legacy code, the MDS tools follow JSHint's mellow philosophy.  JSLint's more rigid approach is achievable with options. Currently the nonew option comes from JSHint. More are likely to follow. Create and vote on enhancement requests.  MDS 1.2 provides five extensions to JSLint:
  • Option to disable === requirement
  • Option to disable curly brace requirement for one-line blocks
  • Option to disable semicolon requirement
  • Option to allow var declarations in 'for' initializers
  • Option to allow side-effects from 'new'
