Also, @BridgeAR shouldn't this return this? (as well as the other one)

Yes, that would be ideal. this will just let inspect() to properly know what to do.


const opts = Object.assign({}, options, {
dept: options.depth === null ? null : options.depth - 1
depth: NumberIsInteger(options.depth) ? options.depth - 1 : options.depth

I'd assume this was a bug (dept instead of depth) but wanted to point out since I'm not sure how this interaction works (inspecting circular events I assume?).
Also, use NumberIsInteger instead of just null check.

That is both correct. The user should only ever pass through null or and integer but it would be possible to pass through other types as well.
