Curious case in JavaScript where you get not exactly the most people would expect

function test() {
  var v = 2;
  var v = v++;
  console.log(v);
}
test();

Why the ++ seems ignored here? at what point the ++ operation is executed?

"v++ increments v to 3 and returns 2" what is the first, increment or return?

• if it increments first, the returned value should be "3"
• if it returns first 2, then after that increments, so the incremented value is 2 and v should be 3...
