Does Promise.from works correctly?

[egorse]

Promise.from(1).then(Promise.from(2)).then(Promise.from(3)).then(console.log); gives 1.

Is that by design?

I had impression it should resolve to last .then as 3.

.then accepts functions only. My bad 😪
Sadly it doesn't throw

Unfortunately it's not allowed to throw as, according to the spec, that's valid behavior. It could log a warning though, and I'd be quite keen to have it do that (whenever the argument is "truthy")

Misread which 'value' meant in 2.2.7.3
