Excluding unwanted keys in Object

Since we can get the desired object key, we can also exclude the unwanted key, using the ES6 rest new feature

const obj = { a:1, b:2, c:3, d:4}//We want to get all attributes except a const {a,... other} = obj

We only need to specify the excluded attributes, and the remaining attributes are the required attributes. This can eliminate the unnecessary attributes very quickly.
