Switch-Case in JavaScript

Switch-case statements in JavaScript provide a way to execute different blocks of code based on the value of an expression. This control flow structure is useful when you have multiple conditions to check against a single variable. Instead of writing a series of if-else statements, switch-case statements offer a more concise and readable solution.

In this article, we'll explore the syntax, usage, and best practices for switch-case statements in JavaScript.

The basic syntax for a switch-case statement is as follows:

switch (expression)
{
    case value1:
        // code to execute if expression matches value1
        break;
    case value2:
        // code to execute if expression matches value2
        break;
    // more cases...
    default:
        // code to execute if expression doesn't match any case
}
