String.charCodeAt is a simple function so you might expect the function call overhead (huge in AS3) to making calling it frequently quite slow. You’d think that there’s no way an charCodeAt-using AS3 function could beat a built-in String function like indexOf. Would you be right? Today’s article examines this special function to see if we might defy conventional wisdom and achieve a performance boost.

Today’s article is about three totally unrelated discoveries I’ve recently made in AS3. These answer three questions I’ve recently had. Should you cache the object you’re looping over with a for-each loop as a local variable? Can you clear a Dictionary or Object with a for-in loop? Is it faster to write your own version of Vector.indexOf? All of these questions are answered in today’s article!
