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