## 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:
|
||
|
|
|
||
|
|
```js
|
||
|
|
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:**
|
||
|
|
|
||
|
|
```js
|
||
|
|
total([1, 1, 3]) // -> 5
|
||
|
|
total([6, 2, -3]) // -> 5
|
||
|
|
total([1, 2, 2]) // -> 5
|
||
|
|
total([0, -2]) // -> -2
|
||
|
|
```
