Discussion on: Javascript var, let and const

[calvintwr]

And not forgetting the best that let has done is to solve nested looping:

for(let i=0; i<100; i++) { for(let i=0; i<500; I++) {}}

Where before you would need to be using i, j, k... until if you have complicated loops with conditionals, you won’t even know if it has conflicted.
