On: How necessary are var, let, and const?

isn't 2 kind of a misdirected optimization for an untyped language?

How is INTENT of immutability ( and with const - now an enforced immutability ) misdirected optimization in any language.

Javascript is dynamically weakly typed but it is still typed, typeof/instanceof exist for a reason.

[catshirt → pm24601]

sorry right- weakly typed.

my point is if you are using a weakly typed language, it doesn't care much about developer intent with respect to type. so why would it be concerned with developer intent with respect to mutability? seems arbitrary.

maybe because developers in general prefer to not have bugs?
