JavaScript includes() Method – Description & Examples
The includes() method in JavaScript is used to check whether an array contains a specific element. It returns a boolean value: true if the element is found and false if it is not. Unlike indexOf(), which returns an index, includes() provides a more straightforward way to check for existence without needing additional comparisons.
This method uses strict equality (===) to determine if an element is present, meaning it does not convert data types. It accepts two arguments: the element to search for and an optional starting index. By default, the search starts from index 0, but if a different index is provided, the method begins searching from that position. If the index is negative, it is treated as an offset from the end of the array.
