Parameter cannot have a question mark and initializer

[leegrey]

Hi. Not sure if you are still maintaining this...

This may be a change in the TypeScript specification since the time you last pushed, but in its current form it gives the error:

"Parameter cannot have a question mark and initializer "

In several situations like this:

public has(listener, context?: any = null): bool

It's happy if you remove the question mark though. :)

「So to fix the compiler error you can simply remove the '?' and leave the default value and it will remain as an optional parameter as you intend.」
