Description

If you know you have two arrays or two objects in hand, and you want to know if they are shallowly equal or not, this library is for you.

Features

• Super light
• No dependencies
• Thoroughly tested

Installation

 npm install shallow-equal --save

or

 yarn add shallow-equal

Usage

 import { shallowEqualArrays } from "shallow-equal";

shallowEqualArrays([1, 2, 3], [1, 2, 3]); // => true
shallowEqualArrays([{ a: 5 }], [{ a: 5 }]); // => false

 import { shallowEqualObjects } from "shallow-equal";

shallowEqualObjects({ a: 5, b: "abc" }, { a: 5, b: "abc" }); // => true
shallowEqualObjects({ a: 5, b: {} }, { a: 5, b: {} }); // => false

You can also use the generic form, shallowEqual. But note that it does runtime type checking in order to decide whether it's comparing arrays or objects, so the convenience comes with a runtime penalty.

 import { shallowEqual } from "shallow-equal";

shallowEqual([1, 2, 3], [1, 2, 3]); // => true
shallowEqual({ a: 5, b: {} }, { a: 5, b: {} }); // => false
