A "let" or "const" variable is said to be in a "temporal dead zone" (TDZ) from the start of the block until code execution reaches the line where the variable is declared and initialized.

In JavaScript, variables declared with let or const are not hoisted to the top of the block scope. If you try to access a variable before it is declared, a ReferenceError will be thrown.
