Regular expression test can't decide between true and false (JavaScript)

Question

I get this behavior in both Chrome (Developer Tools) and Firefox (Firebug). Note the regex test returns alternating true/false values:

> var re = /.*?\\bb         


        

Answer 1

/g (global) regexps will do that, yes.

See this question.

When you write a literal, you're getting a new regexp object every time, so losing the lastIndex state associated with the old object.
