How to use some() Method In Javascript
The some() method uses the function for its evaluation and it executes the function once for each element present in the array. If it finds the object/element in the array then it returns true and stops the execution for the remaining elements otherwise returns false.
Syntax:
array.some( function(currValue, arrIndex, arrObj), this )
Example: This example shows the use of the above-explained approach.
let arr = ["geeks1", "geeks2", "geeks3",
{ 1: "geeks4", 2: "geeks5" }];
let boolVar = arr.some(
value => { return typeof value == "object" });
console.log(boolVar);
Output
true
