How to use every() Method In Javascript
The every() Method checks if all elements in an array pass a test (provided as a function).
Example: In this example we are using every() method for iteration of an array.
let x = 0;
let array = [1, 2, 3, 4, 5, 6];
const under_five = x => x < 5;
if (array.every(under_five)) {
console.log('All are less than 5');
}
else {
console.log('At least one element is not less than 5');
}
Output
At least one element is not less than 5
