Made in response to the amount that I was using lodash.get to update data in a project and needed a better solution. Ability to cache all key chains to avoid garbage and maintain performance. Backwards compatible with lodash.get.

Passing false as the 3rd param will force no cache.

Getting Started

Installation

npm

npm install @chickendinosaur/object-get-property

Usage

const getObjectProperty = require('@chickendinosaur/object-get-property');

let obj = {
	one: [
		{
			three: true
		},
		{
			three: true
		},
		{
			three: true
		}
	]
};

// Trim a custom char.
getObjectProperty(obj, 'one.2.three');
getObjectProperty(obj, 'one[2].three');

// Result

/*
true
*/
