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.
- Super light
- No dependencies
- Thoroughly tested
npm install shallow-equal --saveor
yarn add shallow-equalimport { shallowEqualArrays } from "shallow-equal";
shallowEqualArrays([1, 2, 3], [1, 2, 3]); // => true
shallowEqualArrays([{ a: 5 }], [{ a: 5 }]); // => falseimport { shallowEqualObjects } from "shallow-equal";
shallowEqualObjects({ a: 5, b: "abc" }, { a: 5, b: "abc" }); // => true
shallowEqualObjects({ a: 5, b: {} }, { a: 5, b: {} }); // => falseYou 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
