Welcome to your interview.
The question is on your right: Let, Const, Var Scope And Hoisting. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Can you explain the difference between let, const, and var in terms of scope and hoisting?
