Can you outline the key distinctions between ref and reactive in Vue.js?

After diving into Vue.js recently, I'm finding myself struggling to completely understand the key distinctions between using ref and reactive. Can someone clarify when it's appropriate to utilize ref versus reactive?

Answer №1

After reading an interesting piece by the talented Vue.js expert, Anthony Fu, it is clear that:

  • Refs are seen as basic values
  • Reactives are treated as objects
  • Only the .value property can change refs, while reactives can be mutated with any nested property
  • Reactives resemble regular objects
  • Be cautious with reactive objects as they may lose reactivity when destroyed
  • When watching reactive objects, make sure to wrap them in a function like
    watch(()=>reactiveObj,(newVal,oldVal)....
    , unlike refs which don't need wrapping like
    watch(refProp,(newVal,oldVal)....

To sum up:

My advice is to opt for ref whenever possible
