Const variables in a for loop

Question

Hello Everyone...
Can someone explain this piece of code please.....

for (let i=0;i<10;i++){
const z =i
console.log (z)
}
Why aren't we getting any errors?... Aren't we declaring a const again?

Answer 1

const variables are block-scoped so the lifetime of z ends at the end of every iteration, allowing const z to be redeclared in the next iteration.

Answer 2

jtrh thanks i got it 🌹
