Functions are self-contained blocks of code with their own scope, that can be called by other code and are usually associated with a unique identifier.
|
|
Functions accept input in the form of arguments and can optionally return an output (if no `return` statement is present, the default value of `undefined` will be returned instead).
|
|
JavaScript functions are also objects.
