Combining Inputs into a Single Value

Using Nested Switch Statements

Combining several inputs into a single value is one technique to handle them. When inputs may be expressed as flags or when each input contributes to a different bit of the total value, this method is especially helpful.

Example: The below code will explain how you can combine multiple inputs and use them with switch statements.

Javascript


                    enum Inputs {
    Input1 = 1,
    Input2 = 2,
    Input3 = 4,
}

function handleCombinedInput
    (combinedInput: Inputs[]): void {
    for (const input of combinedInput) {
        switch (input) {
            case Inputs.Input1:
                console.log("Handling Input1");
                break;
            case Inputs.Input2:
                console.log("Handling Input2");
                break;
            case Inputs.Input3:
                console.log("Handling Input3");
                break;
            default:
                console.log("Handling default case");
        }
    }
}

let combinedInput: Inputs[] =
    [Inputs.Input1, Inputs.Input2, Inputs.Input3];
handleCombinedInput(combinedInput);

Output:

Handling Input1
Handling Input2
Handling Input3

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.
