Difference in map between underscore/lodash and jQuery/Zepto.
// Difference in map between underscore/lodash and jQuery/Zepto.
//
// $ allows filtering at the same time; _ does not.
//
// In your client-side JavaScript apps that use _ and $, this can come as a
// surprise since the assumption is that all your map, each, filter, etc. needs
// are fulfilled by _, and you'd be right to use them for speed since they
// alias native methods where available. However, sometimes $ can be useful,
// and this is one such case where that's true.

RegExp.escape(string)

Computes a new version of a String value in which certain characters have been escaped, so that the regular expression engine will interpret any metacharacters that it may contain as character literals.

When the escape function is called with one argument string, the following steps are taken:

  1. Let string be ToString(string).
  2. ReturnIfAbrupt(string).
  3. Let length be the number of characters in string.
  4. Let R be the empty string.
