import { ButtonComponentData, StringSelectMenuComponentData, UserSelectMenuComponentData } from "discord.js";

type Example1 = (
    | ButtonComponentData
    | StringSelectMenuComponentData
    | UserSelectMenuComponentData
);

type Example2 = (
    | StringSelectMenuComponentData
    | UserSelectMenuComponentData
);

const example1: Example1 = {} as any;
const example2: Example2 = {} as any;

if (example1.type === ComponentType.StringSelect) {
    // Type of example1: ButtonComponentData | StringSelectMenuComponentData
}

if (example2.type === ComponentType.StringSelect) {
    // Type of example2: StringSelectMenuComponentData
}
