### sdbmHashAlgorithm
|
|
|
|
This algorithm is a simple hash-algorithm that hashes it input string `s` into a whole number.
|
|
|
|
Use `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)
|
|
}
|
|
// console.log(sdbm("name")) // -3521204949
|
|
// console.log(sdbm("age")) // 808122783
|
|
```
