RESERVED JS NAMES - Martha's Web Resources

Reserved Words in JavaScript
SOURCE: JavaScripter.net
Question: What reserved words are there in JavaScript?>

Answer:  Reserved words of the JavaScript langauge are listed below. (Some of these words are actually used in the Java language, and are reserved in JavaScript for compatibility purposes or as possible extensions.) When choosing names for your JavaScript variables, avoid these reseved words!

abstract  	else  	instanceof  	switch
boolean  	enum  	int  	synchronized
break  	export  	interface  	this
byte  	extends  	long  	throw
case  	false  	native  	throws
catch  	final  	new  	transient
char  	finally  	null  	true
class  	float  	package  	try
const  	for  	private  	typeof
continue  	function  	protected  	var
debugger  	goto  	public  	void
default  	if  	return  	volatile
delete  	implements  	short  	while
do  	import  	static  	with
double  	in  	super

In addition to the above reserved words, you'd better avoid the following identifiers as names of JavaScript variables. These are names of client-side objects, methods, or properties in Netscape Navigator or Internet Explorer:

alert  	hidden  	outerWidth
all  	history  	packages

anchors  	images  	pageYOffset
area  	isNaN  	parent
array  	java  	parseFloat
assign  	JavaArray  	parseInt
blur  	JavaClass  	password
button  	JavaObject  	pkcs11
checkbox  	JavaPackage  	plugin
clearTimeout  	innerHeight  	prompt
clientInformation  	innerWidth  	prototype
close  	layer  	radio
