How to use some() method In Javascript
The Javascript arr.some() method checks whether at least one of the elements of the array satisfies the condition checked by the argument method.
Syntax:
arr.some(callback(element,index,array),thisArg);
Example: In this example, we will check for some elements in the array that are greater than 50 or not. The function returns true as there are elements greater than 50 in the array.
const arr = [25, 33, 22, 45, 67, 1, 32, 223];
console.log(arr.some((element) => element > 50));
console.log(arr.some((element) => element < 40));
console.log(arr.some((element) => element > 70));
Output
true true true
