That's not how let and const work at all, where did you get that impression?

  Have you ever made a for loop using var only to have the variable point to the last value in the iteration ? And had to make a closure using forEach, function or self calling function ? With let you do not have to do that as a new variable is created for each iteration. Instead or reassigned when you use var.
