MORE INFORMATION

For example, suppose you have an HTML page that contains the following two .js files:

//first.js
Var test = 'first';

//second.js
If (test == null) var test = 'second';

When Internet Explorer executes the second.js file, the jscript.dll file re-creates the test variable without looking at the name table. However, Internet Explorer overwrites the test variable that the first.js file created.
