I liked s.meijer's answer and wrote my own version based on his:

function parseTemplate(template, map, fallback) {
    return template.replace(/\$\{[^}]+\}/g, (match) => 
        match
            .slice(2, -1)
            .trim()
            .split(".")
            .reduce(
                (searchObject, key) => searchObject[key] || fallback || match,
                map
            )
    );
}
