This property is particularly useful for JAR management. In earlier releases, if you set this property to a number smaller than 100, JavaScript rounded it up to 100. In 4.0, it does a security check to see if the script can set the property to a number smaller than 100.

Regular Expressions are patterns used to match character combinations in strings.
In JavaScript, you create a regular expression as an object which has methods used to execute a match against a string. You can also pass the regular expression as arguments to the String methods match , replace , search , and split . The RegExp construction object has properties most of which are set when a match is successful, such as lastMatch which specifies the last successful match. Finally, the Array object has new properties that provide information about a successful match such as input which specifies the original input string against which the match was executed. The RegExp Object String Methods Array Properties Signed Scripts For additional power and functionality, scripts can now gain access to normally restricted information.
