collection.equal( )
collection.equal( )
The collection.equal( ) method compares the collection with collection2 and returns true if they are identical (deep comparison).
By default, a non-diacritical evaluation is performed. If you want the evaluation to be case sensitive or to differentiate accented characters, pass the ck diacritical constant in the option parameter.
Note: Elements with Null values are not equal to Undefined elements.
