Return falsy when conversion is not supported about convert

[jonahsnider]

Would it be possible to make the function return null or false when a conversion fails?

Yes, but I don't want to support this. Users should just use the correct units. Forcing everyone to explicitly handle graceful failures because of misspelling the name of a unit is silly, and harms the UX for the vast majority of users. Also, this is only a problem that affects JavaScript users, since TypeScript users will just get a compile-time error if they make the same mistake.

will output the whole library code.

Throwing an error will print the stacktrace of the code where the error occurred. That's built-in JavaScript behavior.

Convert-Units does this already

convert-units is no longer maintained, the last update was more than 5 years ago. If you want functionality to be added you should make a new issue on this repository and request the feature there.

@MrAmericanMike - agreed! Just found this library pretty well same time this was opened & first thing I thought!

It would be very nice if @jonahsnider can think about merging / talking to the owner owner of the package / library convert-units to merge these libraries together so they can be used to return the human phrases of the conversion. > Convert-Units does this already, but does not have support for converting via ["seconds", "secs"] etc.. and only one format which is not ideal.

If these libraries merged both of their great features - it would be amazing 🔥.

@jonahsnider - sorry to convert / not trying to deter but I highly suggest you look at contributing your project into the Math.JS library (better than my last recommendation!)
