Can You Use Multiple Cases in a JavaScript Switch Statement?

Multiple Cases in a JavaScript Switch Statement

In JavaScript, it's not possible to specify multiple cases in a single case statement of a switch construct as shown in the initial code example. To handle such scenarios where multiple cases require the same code execution, the "fall-through" feature of the switch statement can be used.

Consider the revised code:

switch (varName) {
    case "afshin":
    case "saeed":
    case "larry":
        alert('Hey');
        break;

    default:
        alert('Default case');
}

With the fall-through feature, when a case matches, the code execution continues to the next case until a break (or the end of the switch statement) is encountered. This way, the code for handling "afshin," "saeed," and "larry" can be grouped into a single case statement, adhering to the DRY (Don't Repeat Yourself) principle.

Therefore, using the fall-through feature of the switch statement provides a viable solution for handling multiple cases in JavaScript, promoting code efficiency and maintainability.
