![]() ![]() ![]() The default clause of a switch statement will be jumped to if no case matches the expression's value. If none of the cases match, then any code within the `default` block will be executed instead. The switch statement evaluates an expression, matching the expression's value against a series of case clauses, and executes statements after the first case clause with a matching value, until a break statement is encountered. The `break` statement indicates the end of each case and prevents code from being executed in subsequent cases. It evaluates an expression and matches the value to a case clause, executing statements associated with that specific case. The switch statement in JavaScript is a useful tool for performing different actions based on different conditions. ![]() If none of the cases match, the `default` block is executed. It then checks whether the first case expression evaluates to the same value as the result of the input. It is just like else if statement that we have learned in previous page. A switch statement first evaluates its input expression. The `break` statement is used to indicate the end of each case and prevent the execution of the code in the following cases. The JavaScript switch statement is used to execute one code from multiple expressions. In this example, the expression `dayNumber` is evaluated, and the code block associated with the matching case (in this case, `case 3`) is executed. Here’s an example using the switch statement: Statements to be executed if none of the cases match the expression ![]() Statements to be executed if the expression matches value2 Statements to be executed if the expression matches value1 Here’s the basic syntax for the switch statement in JavaScript: The `switch` statement evaluates an expression, matching the expression’s value to a case clause, and executes statements associated with that specific case. A switch works by testing the value of the expression in switch (expression) against the values of each case until it finds one that matches. In JavaScript, you can use the switch statement as a way to perform different actions based on different conditions. The syntax The switch has one or more case blocks and an optional default. It gives a more descriptive way to compare a value with multiple variants. In this blog post, we’ll discuss the syntax of the switch statement and provide an example of how it works. The JavaScript language JavaScript Fundamentals ApThe 'switch' statement A switch statement can replace multiple if checks. Are you looking for a way to perform different actions based on certain conditions in JavaScript? The switch statement is an effective tool that can help you do just that. ![]()
