### sdbmHashAlgorithm
|
|
|
|
This algorithm is a simple hash-algorithm that hashs it input string 's' into a whole number.
|
|
|
|
The function iterates over each character in string 's' and updates in each iteration the 'hashCode'.
|
|
|
|
``` js
|
|
function sdbm(s) {
|
|
let hashCode = 0;
|
|
for (let i = 0; i < s.length; i++) {
|
|
hashCode = s.charCodeAt(i) + (hashCode << 6) + (hashCode << 16) - hashCode;
|
|
}
|
|
return hashCode;
|
|
}
|
|
|
|
// examples
|
|
console.log(sdbm("name")) // -3521204949
|
|
console.log(sdbm("age")) // 808122783
|
|
```
