Loops

Tradicional Loop

Efficient but has too much info:

demo.js

 
const array = [2, 4, 5, 8];
const expected = 5;
let result = 0;
 
for (let index = 0; index < array.length; index++) {
    const element = array[index];
    if(element === expected){
        result = element;
    }
}
 
console.log("result", result); ${2}

Instead

You can make very shortened loop

    const array = [2, 4, 5, 8];
 
    const result = array.filter(item => item === 5);
 
    console.log("result", result);
