JavaScript access string chars as array

Question

Is it ok to do this:

var myString=\"Hello!\";
alert(myString[0]); // shows \"H\" in an alert window

Or should it be done with either charAt

Answer 1

Using charAt is probably the best idea since it conveys the intent of your code most accurately. Calling substr for a single character is definitely an overkill.

alert(myString.charAt(0));
