Drop-in for estraverse that enables traversal over React's JSX and Flow nodes using monkey-patching technique.

You can use estraverse-fb in two possible ways:

• by default, you just require it and it injects needed keys into your installed version of estraverse (it's installed automatically if you don't have it yet):

  var estraverse = require('estraverse-fb');
  /* same as:
      require('estraverse-fb');
      var estraverse = require('estraverse');
  */
  
  estraverse.traverse(ast, {
      enter: ...,
      leave: ...
  });

• alternatively, you can use it manually for selected traversals:

  var jsxKeys = require('estraverse-fb/keys');
  
  estraverse.traverse(ast, {
      enter: ...,
      leave: ...,
      keys: jsxKeys
  })
