How to check if array contains at least one object ?

Question

I want to check if array contains object or not. I am not trying to compare values just want to check in my array if object is present or not?

Ex.

$arr = ['a','b','c'] // normal
$arr = [{ id: 1}, {id: 2}] // array of objects
$arr = [{id: 1}, {id:2}, 'a', 'b'] // mix values

So how can i check if array contains object

Answer 1

You can use some method which tests whether at least one element in the array passes the test implemented by the provided function.

let arr = [{id: 1}, {id:2}, 'a', 'b'];
let exists = arr.some(a => typeof a == 'object');
console.log(exists);
