Languages

Procedural/Imperative

They have specific beginning and end points.
E.g. visual basic
Runs exactly how you define it to run, inflexible.
you define the sequence and iteration.

Declarative
ProLog - programmable logic
define facts and rules


Event Driven
responds to events - buttons being pressed, countdown timers, user entering specific data

Scripting
JavaScript - used to extend the functionality of programs
so we can write our own wee code to do anything!
Image Rollovers!

Macro!!!
Records the keystrokes (instructions) that you make
assigns them to a keystroke
The instructions can then be repeated by pressing the shortcut keystroke (like Control + T)
