Using reduce() method: The array reduce() method in JavaScript is used to reduce the array to a single value and executes a provided function for each value of the array (from left-to-right) and the return value of the function is stored in an accumulator.

Syntax:

array.reduce( function( total, currentValue, currentIndex, arr ), initialValue )

Example 1: This example uses array reduce() method to find the OR of values of an Array using JavaScript.
