This project is used by 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.
var
? Shouldn't this use let
and const
?Yes, but not all situations allow the use of let
and const
, such as when

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.
