 Inside attributes like onclick  As a section of code in the body  Only special cases  As a function in a separate file  Can link to it like the css  We will use

 Collection of statements that can be invoked as a unit  Can take parameters  Can be used multiple times  Can call without knowing what they do or how

function name() { stmt; }

Myscript.js JavaScript option in komodo note that it’s an empty file but it can help you do NOT include the script tag

function name(parm) { stmt; }

 Name is a placeholder  Can be used anywhere in a function  Can be used as many times as you want  Can not change it  MUST supply value when call  Can be different everytime

HTMLJS mypet(‘cow’); mypet(‘dog’); function mypet(pet) { alert(‘my pet: ‘+pet); }

 Order matters  Need different names

HTMLJS mypet(‘Mutt’,’Jeff’); mypet(‘Jeff’,’Mutt’); function taller(big,small) { alert (big+’ is taller than ‘+ small); }

 Jsbin is just like jsfiddle but it allows you to see the console  Console.log( message );
