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

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