the \b flag not working in javascript regrex : I am new to regular expressions and basically just playing around with them in my brower console ,  using MDN as a referance , i tried the below regrex:

    /\bg/g.test('me building and him')

even if i try `/\bg/g` , i still get false, WHY ? 

The MDN definition says the following for `\b`:

> Matches a zero-width word boundary, such as between a letter and a
> space. (Not to be confused with [\b])
> 
> For example, /\bno/ matches the "no" in "at noon"; /ly\b/ matches the
> "ly" in "possibly yesterday".

So why is the `g` at the end of building not being matched ? , can anybody explain ?
