浅复制，深复制同理
```
const fn = () => 1;
fn.a = 2;
fn.f = () => 3;
const obj = Object.assign({}, fn);
const cloneFn = fn.bind();
Object.keys(obj).forEach(key => { cloneFn[key] = obj[key] })
```
```
const fn = () => 1;
fn.a = 2;
fn.f = () => 3;
const obj = Object.assign({}, fn);
const cloneFn = fn.bind();
Object.keys(obj).forEach(key => { cloneFn[key] = obj[key] })
```
