JScript Reserved Keywords

 Previous | Next 

JScript has a number of reserved keywords. These words come in three types: JScript reserved keywords, future reserved words, and words to avoid.

JScript Keywords


JScript Future Keywords

The words to avoid are any that are already the names of intrinsic JScript objects or functions. Words like String or parseInt are included in this.

Using any of the keywords from the first two categories causes a compilation error when your script is first loaded. Using a reserved word from the third set can cause odd behavior problems if you attempt to use both your variable and the original entity of the same name in the same script. For example, the following script does not do quite what you think it should:

var String;
var text = new String("This is a string object");

In this case, you get an error saying that String is not an object. Many cases of using a pre-existing identifier aren't this obvious.
