A bit silly don't you think. I do know it is not a calculator but one would think it would be able to perform on level with a simple hand calculator.

It _does_ evaluate simple arithmetic expressions without building a parser (assuming it is legal JavaScript in the first place). If you want to execute an expression which is not legal JavaScript, you will indeed need a parser for this.

I don't see why the claim silly is made. Silly that JavaScript doesn't have feature X?
