In this article I would like to share with you guys how to use and declare switch statement in JavaScript as our programming language. Switch statement is another type of conditional statement mainly use to check for conditions based on the values that is being provided by our user of our program. The advantage of using switch statement is that it is easy to understand in terms of declaration and usage but the problem with switch statement we are not allow to use logical and relational operators that why many of conditional statements are using if - else statement instead of switch statement.
