js any array
const array = [1, 2, 3, 4, 5];
// checks whether an element is even
const even = (element) => element % 2 === 0;
console.log(array.some(even));
// expected output: true

let array = [1, 2, 3, 4, 5];
//Is any element even?
array.some(function(x) {
return x % 2 == 0;
}); // true
Thank you!

// There's no isEmpty or any method.
// You can define your own .isEmpty() or .any()
Array.prototype.isEmpty = function() {
return this.length === 0;
}
Array.prototype.any = function(func) {
return this.some(func || function(x) { return x });
}
Thank you!
