The let statement declares a block scope local variable, optionally initializing it to a value.

let x = 1;

if (x === 1) {
  let x = 2;

  console.log(x);
  // expected output: 2
}

console.log(x);
// expected output: 1

* Variables defined with let cannot be redeclared.
* You cannot accidentally redeclare a variable.

let x = "John Doe";

let x = 0;

// SyntaxError: 'x' has already been declared
