When I read code, some people use var but other people use let. I read that the let is the block scope, but if I use the var it's still block scope as you cannot use it outside of the for loop. What is the benefit of using let instead of var in the for loop as the below.

 for (let i = 0; i < action.payload.customers.length; i++)

  • "*if I use the `var` it's still block scope as you cannot use it outside of the for loop*" - well, wrong. Just try a loop with `var` and do `console.log(i)` afterwards. – Bergi May 02 '20 at 09:00
