See the example bellow:\n\n```js\nimport { hash, getSeed } from 'cruxhash';\n\nconsole.log(hash('Smile, my dear!')); // returns 2890382619\n\nconsole.log(hash(42)); // returns 1462734105\n\nconsole.log(hash(42, getSeed('my seed'))); // returns 8142968\n\nconsole.log(hash({ a: 10, b: 10 })); // returns 3685477545\n\nconsole.log(hash([1, 2, 3])); // returns 2610324319\n\nconsole.log(hash('コンニチハ, Hello world, Καλημέρα κόσμε 😀')); // returns 1898574527\n```\n\nMost of times, the function [`hash`][hash] is sufficient for making the hash\ncodes. If you need some tampering, pass a number to the `seed` parameter to\nstart the hash algorithm. You can use the the [`getSeed`][getSeed] function to\ngenerate some seeds from strings. Other functions are available, see the\n[Wiki's Page][Wiki] for the complete API.\n\nCRUXHash uses [Murmur3][Murmur3] as the hashing algorithm in most of cases, the\nexception is when hashing 32bit integers, where it uses [Thomas Wang's][Wang]\nshift and multiplication algorithm.\n\n## Contributing\n\nPull requests are welcome.
