IMO, I don't really like it as a switch or the if statements. My issue being the multiple booleans being passed to a single function. I could see it growing to 3, 4, or greater too if more social options were added. I prefer enums. SocialUrl = 'github' // or twitter or w/e return socialConfig[SocialUrl] || defaultSocialConfig or how about: const getConfig = (key, default) => config[key] || default Logic per key value isn't necessary. edit: disregard. Misunderstood the code =)
