### sbdm Hashes the input string into a whole number. Use `String.split('')` and `Array.reduce()` to create a hash of the input string, utilizing bit shifting. ```js const sdbm = str => { let arr = str.split(''); return arr.reduce( (hashCode, currentVal) => (hashCode = currentVal.charCodeAt(0) + (hashCode << 6) + (hashCode << 16) - hashCode), 0 ); }; ``` ```js console.log(sdbm('name')); // -3521204949 ```
