Object code is a blazing fast hash code generator. It generates unique signed integers for objects, arrays, functions, symbols and etc.
You can ise it to index object in a collection, compare objects or just generate unique identifiers.
import { hash } from 'object-code';
const myWeirdObject = {
name: 'Arthur',
age: 20,
address: {
private: true
},
sayHello: function () {
console.log('Hello!');
},
id: Symbol('arthur'),
birth: new Date(2005, 02, 27),
tags: ['person', 'male', 'programmer']
recursive: myWeirdObject,
// etc
};
const hash = hash(myWeirdObject);
// -1352827948
See all unique values at test/values.ts
This package is always seeking for a faster implementation. This means that we don't guarantee that the hash will be the same for two different versions of this package. There will be an warning on the release notes if the hash generation changed.
You shouldn't rely on cross version compatibility, and even if so, you can run some tests before pushing to production :)
This is the result of a benchmark between object-hash
