Array.find()

The find() method returns the value of the first element in the provided array that satisfies the provided testing function. If no values satisfy the testing function, undefined is returned.

JavaScript Demo: Array.find()

     
        const array1 = [5, 12, 8, 130, 44];


        const found = array1.find(element => element > 10);
        
        console.log(found);
        // expected output: 12
        


    

If you need the index of the found element in the array, use findIndex().

If you need to find the index of a value, use Array.prototype.indexOf(). (It’s similar to findIndex(), but checks each element for equality with the value instead of using a testing function.)

If you need to find if a value exists in an array, use Array.prototype.includes(). Again, it checks each element for equality with the value instead of using a testing function.

If you need to find if any element satisfies the provided testing function, use Array.prototype.some().
