delay should throw if its not a number

[gWOLF3]

i came across a scenario where delay was failing silently.

it took a while to debug bc i was not seeing any errors.

i saw that the library was being rewritten in TypeScript, maybe consider adding a type check for the delay field. In my case, I was accidentally passing in a string and it seems like the queue schduler did not even know how to handle that.

where you using the library from typescript? if so the compiler should take care of it, did't it?

As @manast mentioned, I think would be sufficient to have typescript type checking
