The goal today is to write a function that returns the sum of all prime numbers up to a limit. We will do this in two steps: first we're going to write an `isPrime`

function that checks wether or not a number is prime, and then the actual `sumPrimes`

function.

## Check if a number is prime

Write an `isPrime`

function that takes a number as parameter and returns true if this number is prime, false if it isn't.

*Reminder:* A prime number:

- Can only be divided by
`1`

and itself - Is greater than
`1`

## Sum all primes

Write a `sumPrimes`

function to sum all prime numbers up to the parameter `limit`

*included*. Copy you `isPrime`

function from the last assignment to make use of it here.
