|
|
|
|
mix(a, b)
|
|
console.log(a) // {a: 1, b: 2}
|
|
|
|
// Will not override the existing property 'a'
|
|
mix({a: 1}, c, false) // {a: 1, b: 20, c: 30}
|
|
|
|
// Only copy property 'a' and 'c', and override.
|
|
mix({a: 1}, c, true, ['a', 'c']) // {a: 10, c: 30}
|
|
```

|
### mix(receiver, supplier, [override], [copylist])
|
|
|
|
- receiver `Object`
|
|
- supplier `Object`
|
|
- override `Boolean=true` Whether should override the existing property of `receiver`. Default to overriding(`true`)
|
|
- copylist `(Array.<String>)=` If specified, only mix the specific keys in the array. Otherwise, mixin all properties.
|
|
|
|
Extend the object `receiver` with `supplier`, and returns `receiver`.
