Javascript to wait the end of a function including asynchronous MYSQL Queries from node.js? -

-

i'm having javascript problem wait function done before below line called. previous function including javascript mysql queries calls (one of library of node.js). looks like:

function first() {     /**     * lot processes execute     * including asynchronous processes     * running queries using javascript mysql library node.js     */     console.log("i first one!"); }  first(); console.log("i second one!");

then when execute this, happening like:

i second one! first one!

how make them run keeping queue order?

note: confusing question, please jump/follow newly created question again:
everyone please follow/jump new question: node.js mysql detect insert/update completeness of query?

pass callback 2nd function call 1st function. @ end of 1st function, invoke theh callback:

function one(parm, callback) {     //     callback(); } function two() {     // else }  one("my parm", two);
