This. I personally agree with everyone saying const > let, but I just don't find myself caring enough about it to add the inconvenience of typing 5 characters instead of 3 every time I need to create a variable.

You'd think after all these decades I'd no longer be surprised that programmers try so hard to minimize their typing, since it has no demonstrable positive impact on code quality. I guess premature optimization is in the blood of some people.

It's not about working hard to minimize typing, it's more about not wanting to switch from a state of little typing to a state of more typing. Also, it has nothing to do with optimization; I don't think there exists a single person who uses "let" over "const" because of performance reasons. I also don't think anyone uses "let" over "const" because they think it improves code quality.

The right path have to add more value then the path of least residence.

True, which is why we drop any var/let/const for prototyping
