Functions

The topics are:

• Script Functions

• Function Methods

Script Functions

In Script, functions are regular values (also known as "first class" values) which can be manipulated like any other type of value: They can be passed to functions, returned by functions, stored into variables or into objects properties, etc.

For example, the function parseInt is actually a function value which is stored in the parseInt variable:

parseInt-> a function value

This function value can be, for example, assigned to another variable:

myFunction = parseInt

and then called through this variable:

myFunction("-25")-> -25

Function Methods

The only method of functions is:

Script Function Method
