Question

How can i pass enum type defined as parameter. Check at my usage on the bottom of the following picture.

Answer 1

I don't think there's an easy way to say "only support enums" like you want. You have some options though. You can keep adding enums you want to support:

enum Color {};
enum Car {};
type SupportedEnums = typeof Color | typeof Car;
function getText(enumValue: number, typeEnum: SupportedEnums) {
    retrun `${enumValue}(${typeEnum[enumValue]})`;
}

Or, instead of maintaining SupportedEnums, just use any type.

Original answer:

You can refer to the type by using typeof:

getText(enumValue: number, typeEnum: typeof Color): string {
    return typeEnum[enumValue];
}

Answer 2

For any enum, use any.

function getText(enumValue: number, typeEnum: any): string;

To restrict the possible enums, use the union type.

function getText(enumValue: number, typeEnum: typeof Car | typeof Color): string;
