Package Exports
- shallow-equal
- shallow-equal/dist/index.js
- shallow-equal/dist/index.modern.mjs
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (shallow-equal) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
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
