Export assignment forEachRight

• forEachRight(collection: Collection, fcn: Function, thisArg?: any): Collection

• Invokes a function once for each element in a collection, iterating from right to left.

  Notes

  • For dynamic array resizing, the only behavior made intentionally consistent with forEach (iterating from left to right) is when elements are pushed onto the beginning (end) of an array. In other words, for forEach(), [].push() behavior is consistent with forEachRight() [].unshift() behavior.

  • When invoked, the input function is provided three arguments:

    • value: collection value
    • index: collection index
    • collection: the input collection

  Parameters

  • collection: Collection

    input collection

  • fcn: Function

    function to invoke

  • Optional thisArg: any

    execution context

  Returns Collection

  input collection

  Example

  function log( v, index, collection ) {
      console.log( '%s: %d', index, v );
  }
  
  var arr = [ 1, 2, 3, 4 ];
  
  forEachRight( arr, log );
