## CoffeeScript Function : Exercise-15 with Solution

Write a CoffeeScript function that accepts a number as a parameter and check the number is prime or not.

Note : A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself.

HTML Code :

``````<!DOCTYPE html>
<html>
<meta charset="utf-8">
<script src="//jashkenas.github.io/coffee-script/extras/coffee-script.js"></script>
<title>Check a number is prime or not</title>
<body>

</body>
</html>
``````

CoffeeScript Code :

``````
test_prime = (n) ->
if n == 1
false
else if n == 2
true
else
x = 2
while x < n
if n % x == 0
return false
x++
true
console.log test_prime(37)
``````

Sample Output:

```true
```
