(Mostly) nontechnical reply: Both are swing, and they share many figures, though sometimes it isn't obvious. The primary difference is that ECS typically rotates as the patterns are being danced, while WCS is danced in a "slot." Also, WCS music is generally a bit slower than ECS music.
You can find plenty of online videos that illustrate both dances, which may be more useful to you than verbal explanations.
