# Logical Operators

Logical operators work with the boolean values `true` and `false`.

* Logical AND: `a && b`

  ```
    true && true  // is `true`

    true && false  // is `false`

    false && true  // is `false`

    false && false  // is `false`
  ```

  If the left-hand side is false, the right-hand side is not evaluated.
* Logical OR: `a || b`

  ```
    true || true  // is `true`

    true || false  // is `true`

    false || true  // is `true`

    false || false // is `false`
  ```

  If the left-hand side is true, the right-hand side is not evaluated.
