Only applicable to DOM element arrays, cannot process string or number arrays. 2. The "duplicate" here refers to two elements that are actually the same element (determined by strict equality "==="), for example, elements with the same attributes but different nodes are not considered duplicate elements. 3. In jQuery 3.0, this method has been deprecated, it's just an alias for jQuery.uniqueSort(). Please use that method instead. ## Syntax _$_.unique( array ) | Parameter | Description | | :--- | :--- | | _array_ | Array type The specified DOM element array. | * * jQuery Miscellaneous Methods](#) [](#)(#) (#)[](#)
