# Accessor function
|
|
|
|
A wrapper for property accessors supporting functions, property strings or constant values.
|
|
|
|
[](https://nodei.co/npm/accessor-fn/)
|
|
|
|
## Quick start
|
|
|
|
```
|
|
import accessorFn from 'accessor-fn';
|
|
```
|
|
or
|
|
```
|
|
var accessorFn = require('accessor-fn');
|
|
```
|
|
or even
|
|
```
|
|
<script src="//unpkg.com/accessor-fn"></script>
|
|
```
|
|
|
|
## Usage example
|
|
|
|
Given an object
|
|
```
|
|
var obj = {
|
|
a: 1,
|
|
b: 2
|
|
}
|
|
```
|
|
|
|
Use `accessorFn` to access object values via property strings or transformation functions:
|
|
```
|
|
var aFn = accessorFn('a');
|
|
aFn(obj); // 1
|
|
|
|
var sumFn = accessorFn(d => d.a + d.b);
|
|
sumFn(obj); // 3
|
|
|
|
var constantFn = accessorFn(7);
|
|
constantFn(obj); // 7
|
|
``` |
