Why do we need a const referral ?

The click event works fine even without defining const, what is it for?

I am not sure what is meant by const referral. But if you are saying that click handling function is treated as a constant then yeah, it is to make sure that handling function is not altered in anyway.

Are you implicitly creating a global?

If you mean you leave off "const" where a variable is created, that causes the variable to be created as a global instead of a local constant. The code might work, but it's considered bad practice. And if you were running in "strict" mode it would cause an error and not be allowed at all.
