Switch Statement in JavaScript

The switch statement performs different actions based on different condition.

It can be called as the replacement of multiple nested if-else statements.

The JavaScript Switch Statement

  • The switch statement is used to select one of many code blocks to be executed.
  • Switch case is useful for menu based application.


How Switch Statement works?

  • At first, the switch expression is evaluated once.
  • The value of the expression is compared with each of the case.
  • If there is a match, the associated block of code is executed i.e., only one case will be executed.
  • If break is not written after each of the code blocks, all the cases are executed after execution of the matched case.
  • The default portion is executed only when the user inputs a wrong value(other than the case values).
