Reactive

Returns a responsive copy of the object

Const obj = reactive ({count: 0})

Responsive transformations are "deep"-- it affects all nested property. In an ES2015 Proxy-based implementation, the returned proxy is not equal to the original object. It is recommended that you use only responsive proxy to avoid relying on the original object.

Type declaration:

Function reactive (target: t): UnwrapNestedRefs

Prompt

Reactive will unpack all deep refs while maintaining the responsiveness of the ref.

Setup () {

Const count = ref (0)

Const state = reactive ({})

State.count = count

/ / ref will be unpacked

Console.log (count.value = state.count)

Const addRef = () = > {

Count.value++

}

Return {

Count

AddRef

}

}
