Total

JS also provide another type of loop than the while

for..of

for..of loops are used to iterate over a value, for example you can iterate over an array:

let heroes = ['Superman', 'Batman', 'Onepuchman', 'Spiderman', 'Ultraman']

// ↙ the for of  ↙  keywords
for (let heroe of heroes) {
  // <- the value we iterate over
  //  ↖ variable declaration, will be each elements from the value
  // in this case, heroes, an array
  console.log(heroe)
}

From the value we have used so far, only string and array are iterable.

Instructions

Declare the function total that compute the sum of all the values from the given array

If the array is empty, total should return 0

Example:

total([1, 1, 3]) // -> 5
total([6, 2, -3]) // -> 5
total([1, 2, 2]) // -> 5
total([0, -2]) // -> -2
