  It’s calling a function without a parameter.

  You know how in math you had something like:

  f(x) = x²

  Not all functions need parameters though. The function:

  f(x) = 2

  does not even use the provided x! So just leave it out:

  f() = 2

  Similarly, you could give a function two parameters:

  f(x, y) = x + y

  Programmers use functions to primarily organize their code. Otherwise it would get very unreadable very quickly. Those function are usually a bit more complicated than a single line, like.

  Dog.walk() would call the walk() function of “Dog”. Some valid code could be:

  Dog.walk()
  wait(10)
  Dog.stop()
  

  This code would make the dog walk for 10 seconds assuming every function used is actually defined somewhere.
