The && and || operators are called short-circuit operators. They will return the value of the second operand based on the value of the first operand.The && operator is useful for checking for null objects before accessing their attributes. For example......

However, where the generalization for one argument outcome may not be enough, a short-circuit operator may be used. An example is if x then y else false. The short-circuit operator allows the program to evaluate the first argument, with any side effects of that argument, and then evaluate...

JavaScript also offers the bitwise logical AND operator (&). Unlike&&, the bitwise operator performs a bitwise operation on each operand regardless of the outcome of the previous operand. This can lead to unexpected behavior if you intend for short-circuit evaluation. ...
