faithful: deserving trust ; keeping your promises or doing what you are supposed to do.

Minimalistic Scala.js promise/future implementation that does not violate parametricity.

Key features:

• lightweight: 50 SLOC, about 2 kB of uncompressed JavaScript (that’s about 50 times smaller than depending on Scala’s Future),
• efficient: 2 times faster than Scala’s Future and 5 times faster than JavaScript’s Promise,
• parametric: you can safely implement Monad[faithful.Future],
• reasonable: exceptions are not silently swallowed.
