Why is `($ 4) (> 3)` equivalent to `4 > 3`?

Question

I noticed as I was playing around with Haskell today that it is possible to do something like

($ 4) (> 3)

which yields True

Answer 1

($ 4) is the function that takes a function and applies 4 to it.

(> 3) is the function that takes a number and checks if it is greater than 3.

So by giving the latter function to the former, you are essentially applying 4 to the function that checks if its input is greater than 3, and thus you get True.
