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
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.
