Web Sockets, Web Workers, Service Workers… these are terms you may have read or overheard. Maybe not all of them, but likely at least one of them. And even if you have a good handle on front-end development, there’s a good chance you need to look up what they mean. Or maybe you’re like me and mix them up from time to time. The terms all look and sound awful similar and it’s really easy to get them confused.
