Switch case in javascript can be defined as an equivalent of an if-else statement. In javascript, situations where an expression produces different outputs with respect to different cases can be handled by switch case. If the number matches, we'll display the output otherwise, we'll have to write an else statement asking the user to enter a valid number.Īs we can see that the above process is quite complex. Then we'll write seven if statements where we'll compare the variable with the number associated with each day of the week. We'll take the user input and then store it in a variable. ![]() ![]() Now to achieve this, we can use the if-else statement. The app will simply take a number between 1 to 7 and display the day associated with it (i.e., 1 will be Monday, 2 will be Tuesday, and so on). Imagine we are making a website to display the day of the week. In this article, we will extensively discuss the switch case in javascript. The switch statement evaluates an expression, matching the expression's value to a case clause, and executes statements associated with that case, as well as statements in cases that follow the matching case.
