      &= (Binary And Equality)

      Binary and equality operator:

      • Performs the binary and operation if the first operand is of boolean, numeric, floating or date-time type. It throws an exception when the second operand is of not appropriate type.
      • Evaluates the intersection if both operands are strings or the first operand is an array.
      • Throws an exception otherwise.


      var i = 1;
      i &= 2;
