I am an EPUB object model aspiring to be standards compliant.

// eslint-disable-next-line @typescript-eslint/explicit-module-boundary-types
export function Properties(Base) {
    return class Properties extends Base {
        properties() {
            const properties = this._resolve('./@properties');
            if (properties) {
                // normalize spaces and split space separated words
                return properties.replace(/\s+/g, ' ').split(' ');
            }
        }
    };
