I solved this, but at first time I tryed thi way and don’t get well why don’t work.
Why total =+ i dont return 20?

Your code so far


// Setup
var myArr = [ 2, 3, 4, 5, 6];

// Only change code below this line
let total = 0;
for(let i = 0; i < myArr.length; i++){
total += i
}

console.log(total)

total =+ i is the same as total = +i, you are just using the assignment operator and assigning the value of i to total
instead total += i is equal to total = total + i

and also i is the index, not the number inside the array, so it doesn’t work the same

Remember, you want to sum the contents of the array. If your som isn’t referencing the array in some way, that’s probably a bad sign.
