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.
