RegEx for maximum length in JavaScript

How can I limit the length of a string matching a RegEx

I assumed that var sixCharsRegEx = /^.{6,7}/ would only match strings of lengths 6 or 7

What am I missing?

you must use end of string symbol $

like this ^.{6,7}$

You are missing the end anchor:

var sixCharsRegEx = /^.{6,7}$/

Match the start and the end.

var sixCharsRegEx = /^.{6,7}$/;

You are missing closing dollar at the end. Correct one is: /^.{6,7}$/
