I am using the following code in a function:

setTimeout("doSomething(var1)",10000);

But, I also have var1 available as global variable. After 10000 milliseconds, will it call the local var1 or the global var1?

This:

setTimeout('doSomething(var1)', 10000);

will pass the global variable var1,

And this:

setTimeout(function() { doSomething(var1); }, 10000);

will pass the local variable var1.

It will pass the the global variable named var1.
