... Is Not a Function TypeError (JS)

Question

This has happened multiple times with different codes and I have no idea why it is happening.

My function 'like()' is getting called when I click the like button. Although it being clearly defined (in the right scope) it continues to say:
"Uncaught TypeError, like is not a function"

Answer 1

That happened as a result of name clashing, what I mean is that, you defined a variable and function with the same name.
That's what confused javascript.

But this runs without error https://code.sololearn.com/W9GJfJG5zd70/?ref=app
