Which is better: switch statement or if else statement

Answer 1

if() and else{} can use && and ! easily....
While switch not but shorten....

Answer 2

Switch statements are used for aesthetics & code readability. Instead of using 10 or more "else if"s, if you use a switch statement , you need fewer keystrokes as well. There is no performance advantage of using one over the other. I use JavaScript.
