FAQ

This project is used by [decaffeinate][decaffeinate] to add variable
declarations to converted CoffeeScript code. This project is not intended to
allow you to write JavaScript without variable declarations, as I consider that
a bad practice for the same reasons it's a bad practice in CoffeeScript.

Yes, but not all situations allow the use of let and const, such as when
the variable binding takes advantage of
hoisting.
If you want let and const you can use this library in combination with
esnext which will turn all eligible var
declarations into let or const` as appropriate.
