A slightly briefer version of ```from```, which could be set as
```Object.from```
```const from = (i,o={},...p)=>p.map(k=>i[k]&&(o[k]=i[k]))&&o```
Usage
```let obj = from(user.profile,{otherData:"other
data"},"firstName","lastName")```
and
```
Object.from = from;
let obj = {};
Object.from(user.profile,obj,"firstName","lastName","not" /* not included
if not property of input object */);
```
