Comment counter function fix

[Yothu]

Excellent and beautiful project guys! I only have one minor issue.

Issue

choose-your-pokemon/src/scripts/modules/comments.js

Lines 23 to 26 in 7ffcf1d

	const commentCounter = (length) => {
	if (length === undefined || length === null) return 0;
	return length;
	};

The name of the commentCounter function does do not reflect its functionality, because it gets from the very beginning the value that it is supposed to return, in this case, the length of the comment array. What it is actually doing is checking that the length of the comment array is valid.

Suggestion

To fix this issue I would recommend that in the commentCounter function put as a parameter the array of comments, and then return the length of the array.
