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

230,688 PointsAre 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.

17,595 PointsI 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.
