difference between globals and predef in .jshintrc?

问题

What the difference and purpose of having both of them in the .jshintrc? When I want to add a variable to be ignored, which one is the best one I should use? Also I can't find 'predef' in http://www.jshint.com/docs/options/

回答1:

It seems like predef is deprecated and you should use globals instead.

More information here

回答2:

At JSHint Doc page http://www.jshint.com/docs/ "predef" is mention for use inside .jshintrc file, wile word "globals" is used only once for inline directive (those that are inside .js files)

So examples would be :

• inside .jshintrc file

  "predef" : [ // Extra globals
               "angular",
  ]
  

• inside .js files

  /* global app: false */
  

So it would be better to use different words when doing the same but in different places.
