Functions as first-class objects

In JavaScript, functions are first-class objects, because they can be treated like any other variable.

  • They can be assigned to variables.
  • They can be properties of an object called methods.
  • They can be item in array.
  • They can be passed as arguments to a function.
  • They can be returned as values of a function.
