sharp-switch

Simulate what C# switch syntax for assigning a value to a variable depending on an expression does.

Install

npm install sharp-switch

Usage

There is this interesting syntax in C# that lets you assign a value to a variable using a switch statement. Here is what it looks like in C#:

string type = product[0] switch
{
  "01" => "Sweat shirt",
  "02" => "T-Shirt",
  "03" => "Sweat pants",
  _ => "Other",
};

I wanted to make something similar in typescript, here's an example of what I came up with:

import { sharpSwitch } from "sharp-switch";

const someValues = <const>["test1", "test2", "somethingElse"];

for (const value of someValues) {
  console.log(
    sharpSwitch(value, <const>{
      test1: "abc",
      test2: "def",
      default: "default value",
    })
  );
}

Using as const values will help with the returned types of the function.
