How to use Nested Switch Statements In Typescript

Combining Inputs into a Single Value

Another approach to handling multiple inputs is by using nested switch statements. This method is suitable when the inputs are independent of each other and need to be evaluated separately.

Example: The below code uses nested switch statements to handle multiple inputs within them.

Javascript


                    function handleInputCombination
    (input1: number, input2: number, input3: number):
    void {
    switch (input1) {
        case 1:
            switch (input2) {
                case 2:
                    switch (input3) {
                        case 3:
                            console.log
                                ("Handling input combination 1, 2, 3");
                            break;
                        default:
                            console.log
                                ("Handling default case for input3");
                            break;
                    }
                    break;
                default:
                    console.log
                        ("Handling default case for input2");
                    break;
            }
            break;
        default:
            console.log("Handling default case for input1");
            break;
    }
}

handleInputCombination(1, 2, 3);

Output:

Handling input combination 1, 2, 3

How to Use a Typescript Switch on Multiple Inputs ?

In TypeScript, switch statements offer a succinct method for managing several conditions depending on the value of an expression. However, the conventional switch syntax may not seem sufficient when handling numerous inputs.
