A copy of Java's string hashcode method for js

/**
 * Returns a hash code from a string
 * @param  {String} str The string to hash.
 * @return {Number}    A 32bit integer
 * @see http://werxltd.com/wp/2010/05/13/javascript-implementation-of-javas-string-hashcode-method/
 */
function hashCode(str) {
    let hash = 0;
    for (let i = 0, len = str.length; i < len; i++) {
        let chr = str.charCodeAt(i);
        hash = (hash << 5) - hash + chr;
        hash |= 0; // Convert to 32bit integer
    }
    return hash;
}

function hashCode(s) {
    for(var i = 0, h = 0; i < s.length; i++)
        h = Math.imul(31, h) + s.charCodeAt(i) | 0;
    return h;
}
hashCode(""); // 0
hashCode("js"); // 3401
