What are the different methods for iterating over an array?

There are several methods to iterate over an array in JavaScript. The most common ones include for loops, forEach, map, filter, reduce, and for...of. Each method has its own use case. For example, for loops are versatile and can be used for any kind of iteration, while forEach is specifically for executing a function on each array element. map is used for transforming arrays, filter for filtering elements, reduce for accumulating values, and for...of for iterating over iterable objects.
