WebThis can pay off if you have large arrays which are frequently searched, since the implementation of associative arrays will perform better than array-traversing loops. It won't suit every use case though, since it cannot handle duplicates (though you can use the value as a counter, instead of just 1 as above), and it cannot handle an empty index. WebMay 28, 2024 · The Length check has the effect of avoiding the construction of an enumerator object when the function is given an empty array, so the function might perform better for such arrays. However, since the check itself has a cost, it will perform worse for the most common cases, where the array is not empty. In other words, it's not useful.
