The return statement in line 14, Returns from the function or it just return from the if condition? and how javascript return works?

 HashTable.prototype.insert = function(key, value) {
    var index = this.hash(key);
    if (!this.buckets[index]) {
    this.buckets[index] = new HashNode(key, value);
    }
 
    else if (this.buckets[index].key === key) {
    this.buckets[index].value = value;
       }
     else {
    var currentNode = this.buckets[index];
    while (currentNode.next) {
      //updaton part
      if (currentNode.next.key === key) {
        currentNode.next.value = value;
        return;
      }
         currentNode = currentNode.next;// to determine last node
    }
    currentNode.next = new HashNode(key, value);
      }
    };
