JavaScript Definitions

How functions are defined.

How they are used and how they are called.

Advanced



Step 4

The apply() Method

Self Invoked Expressions

Functions that run immediately (mostly historical, still useful sometimes).

Advanced


Step 7

JavaScript Closures

Functions that remember their scope

Learn how functions can remember variables after the outer function finishes.

Advanced


Step 8

Function References

Function Object Methods & Properties.
