![]() ![]() ![]() We are also going to add two new drinks, a latte and mocha, each priced at $3.00 (the same as a macchiato). So that we can reuse our console.log() statements. However, in this example, we are going to change We are going to use the above example to illustrate how to use multiple cases. Instead of writing multiple new cases with their own blocks of code, we can instead use more than one Let’s say that our barista has added two new drinks to the menu, and those drinks cost the same as a macchiato. But what if we want to have multiple cases yield the same output? In our above example, we used a single case for each expression, and each expression had a different output. ![]() Keyword to ensure that when our expression is met, our program stops searching through cases. If we don’t include a break statement, our program will keep evaluating statements even after one has been met. Keyword at the end of every case statement. Statement, which in this case is a message that states In addition, if we had entered an invalid drink name, our code would have returned the contents of our “ To be equal to a different drink, the corresponding price for that drink would appear. When we run our program with the variable Here’s an example of an if statement in JavaScript:Ĭonsole.log("The price of an Americano is $2.60") Ĭonsole.log("The price of a cappuccino is $2.75") Ĭonsole.log("The price of a macchiato is $3.00") Ĭonsole.log("The price of an espresso is $2.40") Ĭonsole.log("This drink is not available") Statements evaluate whether a statement is true or false, and only run if the statement evaluates to true. In JavaScript, the most common form of conditional statement is the Conditional statements evaluate whether a condition is met based on the outcome of a true and false statement.Ĭonditional statements could be useful if you wanted to verify that a user had filled in all the forms on an order page, or to display a message to a user about a product offer only when they are signed in. JavaScript Conditional Statements RefresherĬonditional statements allow you to run code if a certain condition is met and not execute a block of code if that condition is not met. We will also explore how to use multiple cases with the switch statement to create more advanced expressions. In this tutorial, we are going to discuss how to use the JavaScript switch expression case statement to create conditional statements. , and you consent to receive offers and opportunities from Career Karma by telephone, text message, and email.
