A better way to react with state

export const SameScopeMetadataKey = Symbol('SameScopeInjectionParams');
export const SameScope = () => (
// eslint-disable-next-line @typescript-eslint/explicit-module-boundary-types
target, _propertyKey, parameterIndex) => {
    let sameScopeInjectionParams = [];
    if (Reflect.hasMetadata(SameScopeMetadataKey, target)) {
        sameScopeInjectionParams = Reflect.getMetadata(SameScopeMetadataKey, target);
    }
    else {
        Reflect.defineMetadata(SameScopeMetadataKey, sameScopeInjectionParams, target);
    }
    sameScopeInjectionParams[parameterIndex] = true;
};
