Answer 2

There's no known disadvantages of using "let"

Answer 3

Well, let makes a variable only able to be accessed in the block it's in, while var allows it to be used in the entire function (for ex script tags) that they are declared in

Answer 4

Using let might feel more limiting than var, but it's the safer option.

Avoid var.
It's the old way. It's problematic and introduces unexpected bugs because of non-standard behavior.
