Five Lesser-Known JavaScript Array Methods: Mastering Javascript
Exploring Lesser-Known JavaScript Array Methods
JavaScript arrays are incredibly versatile, offering a plethora of methods for various operations. While methods like map
, filter
, and reduce
are widely used, there are several lesser-known methods that can be equally beneficial. In this article, we'll explore five such methods, providing examples to illustrate their usage.
Array.from()
Array.from()
is a powerful method that creates a new, shallow-copied Array instance from an array-like or iterable object. This is particularly useful when dealing with objects that resemble arrays but do not have all their methods, such as NodeLists in the DOM or function arguments.
Array.of()
Array.of()
creates a new Array instance with a variable number of arguments, regardless of the number or type of the arguments. This is different from the Array constructor, which behaves differently when given a single numeric argument.
