pkg.go.dev/io/ioutil says “As of Go 1.16, the identical performance is now supplied by package deal io or package deal os, and people implementations needs to be most popular in new code.”
Does this imply?: utilizing straight package deal io or os is sufficient and higher than ioutil. so do not use ioutil.
In that case, why isn’t this package deal faraway from customary go library? I do know Go goals simplicity. Wouldn’t or not it’s higher if the non-recommended package deal was eliminated?
If i flawed, excuse me 
Notice: I’m beginner about programming. Thanks.
