You should be able to do return match != null, which will capture null and undefined without any of the other falsy values

You can just return here: return !!this._rawValue.find(...).

I found returning !!this._rawValue doesn't work.
Changed to null != this._rawValue.find....

If you only care about the presence of the value, you can use some instead of find:
return this._rawValue.some(v => toggle.value != null && v === toggle.value);There was a problem hiding this comment.
