Required Functions

This function directly requires the following functions which are included automatically:

  • is()
    Tests to see if two or more values are exactly the same. This is similar to === but will also indicate that NaN is NaN and will indicate that -0 is not 0.
  • slice()
    Slice does not modify the original array, but instead returns a shallow copy of elements from the original array.

Requiring Functions

This function is directly required by the following functions:

  • intersect()
    Gets a new array that will be the intersection of two arrays.
  • union()
    Creates a new array which will contain all of the items of the two given arrays. Different from concatenation because the number of times a value occurs will never exceed the maximum number of times it was found in one of the arrays.
