How to eliminate error: "Implied eval is evil"

Question

I'm trying to make my code JavaScript "strict", so I'm running it through JSLint to ensure my code is compliant.

However, on the following code:

setTimeout("getExtJs()", 2000);

I receive the following error:

Implied eval is evil. Pass a function instead of a string.

How do I make my code JavaScript "strict"?

Answer 1

setTimeout(getExtJs, 2000);

Note that there are no quotes around getExtJs, I am passing the function not a String.

EDIT: As noted in the comments the reason why JSLint is upset is that when the first argument is a String it is processed as code to be executed in the same manner as eval()

See https://developer.mozilla.org/en/window.setTimeout

To find out why eval() (and by extension using Strings as the 1st argument here) is evil see the Mozilla Developer Network entry for eval.
