    • Tweetables:

    • “My understanding is that emitting in Vue is the way that you pass data from a child component to its parent. It allows you to create your own events and you can use it wherever you want to, in a component to emit some data backup to its parent.” — @fimion [0:03:23]
    • “I think, it may also be that you don't necessarily need the information directly from callbacks, but you need that information available for something else that would happen.” — @fimion [0:14:56]
    • “If you're looking at a Vue like a page, where all you care about is what the template layout of it is, I feel that's more important to be at the top than the script.” — @fimion [0:18:40]
    • “Since emit does not return a value, you can't actually run validations through emit.” — @fimion [0:33:12]
