>Solution :

Hi it appears you are new to javascript. There are a lot of online resources on javascript fundamentals, and those places will probably provide more benefits for a beginner.

I googled a random one:
https://javascript.info/function-basics#functions-comments

In that section, the code sample uses a "isPrime" function within a "showPrimes" function.
