What is the use of the every() method in JavaScript Arrays ?
The every()
method in JavaScript is used to check whether all elements in an array satisfy a particular condition. It returns a boolean value – true
if all elements meet the specified condition, and false
otherwise.
Example: Here, the every()
method is used to check if every element in the numbers
array is even. Since all elements in this case are even, the every()
method returns true
.
Javascript
let numbers = [2, 4, 6, 8, 10]; // Check if all numbers are even let allEven = numbers.every( function (num) { return num % 2 === 0; }); console.log(allEven); // Output: true |
Output
true
