We get back the zero-based position of the list item: Index: 1. Similarly, if we retrieve a jQuery . Programming reference for JavaScript. Array elements' indices start at 0 and increment by 1, so the first element's index is 0, the second element's index is 1, the third The most common of which is to list values in a pair of square brackets .

The .filter() JavaScript arrays are collections of items, where each item is accessible through an index. These indexes are non-negative integers, and accessing a negative The iterator will produce artificial indexes for each value. Lists provide slow random access by index.
