Answer 1

Languages evolve. It is prudent to reserve a few keywords that might come in use later. According to the ECMA standard, class is a Future Reserved Word.

If you did not reserve them, introducing new keywords could conflict with existing code (which already might be using the word for other things). Happened with Java and assert.
