# Exercise 05 - sumAll

Implement a function that takes 2 integers and returns the sum of every number between(and including) them:

```javascript
sumAll(1, 4) // returns the sum of 1 + 2 + 3 + 4 which is 10
```


## hints

Think about how you would do this on pen and paper and then how you might translate that process into code:
- create a variable to hold the final sum
- loop through the given numbers ([link](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Loops_and_iteration))
- on each iteration add the number to the sum
- return the sum after finishing the loop
