> test()Error in test() :promise already under evaluation: recursive default dispute reference or previously problems?

If ns substitute the definition of f in that of g, then the error walk away.

You are watching: Promise already under evaluation: recursive default argument reference or earlier problems?

I was wondering what the error was? just how to exactly it if don"t instead of the meaning of f in the of g? Thanks!

Update:

Thanks! 2 questions:

(1) if duty test further takes an argument for f, will certainly you include something choose test ? In cases with more recursions, is the a good and safe exercise adding much more .?

(2) if f is a non-function argument, for instance g and test , will utilizing the same name for both formal and also actual non-functional debates a an excellent and safe practice or that may reason some potential trouble?
