Recently, I ran some of my JavaScript code through Crockford's JSLint, and it gave the following error:     Problem at line 1 character 1: Missing "use strict" statement.   Doing some searching, I realized that some people add "use...
This code works alerts "ok" in all browsers except Chrome:  eval("var outer = 0; function test() {'use strict'; outer = 1; } test(); alert('ok');");   (Try it on jsfiddle).  All I'm doing is referencing an outer va...
