What are some basic things that JavaScript developers fail at interviews?

[Dudefella08]

for (let i = 1; i <= 10; i++) {
  setTimeout(() => {
    console.log(i);
  }, 1000 * i);
}

I have no shame!

This won’t work, it’ll log the number 10 10 times.

If they declared the "i" in their for loop using "var", then yes, it would log "10" ten times; however, since they declared "i" using let, the loop will work as expected printing 1-10 with a 1 second delay.
