Descriptions of &&(AND) and || (OR) might be misleading and less accurate:
- `&&`: AND used to perform logical AND operation. It gives true if both the operands have true value.
- `||`: OR used to perform logical OR operation. It gives true if either of the operands have true value.For instance, || gives true if the 1st operand has a true value, and it will not try to evaluate the 2nd operand.
It might be helpful to mention & and | first, and then present a comparison between & and &&, as well as | and ||.
