Logical and logical OR operator principles

1. Logical OR Operator | |

A left-to-right operation that returns the operand if the current operand is true, or until the right operation is encountered until the operand is true, or until the last. When the last operand is evaluated, the last operand is returned without concern for the true or false state of the last operand

<script>         Console.log (0| | 0| | undefined| | NULL);</script>

Print out:

Null

2. Logic and Operators &&

A left-to-right operation that returns the operand if the current operand is false, or until it is encountered as a false operand, or until the last. When the last operand is evaluated, the last operand is returned without concern for the true or false of the last operand

<script>        console.log (1 && 3 && "SDF" && null);</script>

Print out:

Null
