Invoke the forEach method within a lambda function and assign the output to a variable

In order to achieve my goal, I am looking for a way to take an array as input and save the result for future use. Unfortunately, I do not have permission to create additional functions. As a result, the code must accurately reflect what result should be.

let array = [[1,2,3,4,5,10],[1,2,3,4,5,20]];
let result;
array.forEach(function(el) {
    if(el[5] == 10) {
        result = el; //need to store this value in a variable
    }
});

I realize that something is missing here and I can't seem to pinpoint what it is. Any guidance on how to make this implementation successful would be greatly appreciated.

Answer №1

When you are looking for specific elements in an array, it is important to use a filtering method.

let numbers = [[1,2,3,4,5,10],[1,2,3,4,5,20]];
let filteredNumbers = numbers.filter((num) => num[5] == 10)

Answer №2

Implement the use of the filter() method.

const filteredArray = array.filter(item => item[5] === 10);
