Manchester-NW5-Yousef Shaikhan-Javascript-week3 - #140

Thanks for making a pull request for JS core week3.
A couple of general comments (which I always look out for :-) .

It is good to keep your code tidy - with proper indentation. So exercise B-While-loop, your evenNumbers function is a little untidy.

The second point is about commenting. It is a good habit to get into (think I said that before). function evenNumbersSum(n) provides a good example. Without a comment it is not clear if the function sums even numbers up to n or sums the first n even numbers (the instructions say the latter of course. It takes time to add these refinements but is worthwhile in the end.

Your E-for-loop exercise1 is a little odd. You added a for loop inside the while loop rather than replace. It gives a lot of output. exercise2 here looks good though.

You didn't manage to convert tube stations to upper case. Do you know this string function toUpperCase()?

A number of tests are failing - mostly because the code hasn't been implemented. Did you run out of time? Ithink your factorial function is close - just a syntax error result *= i not result* =i

Good effort though Yousef so thankyou.
