Monaco Editor Playground Code

const value = /* set from `myEditor.getModel()`: */ `type CarBrand = "Toyota" | "BMW" | "Mercedes" | "Audi";

const car: CarBrand = ""`;

// Hover on each property to see its docs!
const myEditor = monaco.editor.create(document.getElementById("container"), {
    value,
    language: "typescript",
    automaticLayout: true,
});

Reproduction Steps

Open playground url, and input const car: CarBrand = ""
