Matching exact string with JavaScript

Question

How can I test if a RegEx matches a string exactly?

var r = /a/;
r.test(\"a\"); // returns true
r.test(\"ba\"); // returns true
testExact(r, \"ba\")         


        

Answer 1

If you do not use any placeholders (as the "exactly" seems to imply), how about string comparison instead?

If you do use placeholders, ^ and $ match the beginning and the end of a string, respectively.
