Accessor function

A wrapper for property accessors supporting functions, property strings or constant values.

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
