Generating IOTA addresses from a seed: API call Get_new_addresses()

// The snippet is a part of the IOTA Developer Essentials project. You can reach it at https://hribek25.github.io/IOTA101/
// Complete description and story behind the snippet is available at: https://hribek25.github.io/IOTA101/Allchapters_javascript.ipynb.html#0FF479CB6C0A
// Requirement: IOTA Javascript Library (!npm install iota.lib.js)

var IOTA = require('../../node_modules/iota.lib.js/lib/iota');

//For this particular task the Node URL is not important as it will not be contacted at all
//However it has to be well - formatted URI
var NodeURL = "https://nodes.thetangle.org:443";

var MySeed = "WKQDUZTGFKSSLACUCHHLZRKZBHSDSCEBHKUPDLKFBQALEBKDMFRPUQGZRXAADPG9TSRTZGGBZOFRJCFMM";

var iota = new IOTA({
    'provider': NodeURL
});

//Let's generate 3 addresses using default security level=2.
//It is deterministic function - it always generates same addresses as long as the Seed, Security Level and Index are the same

// Please note, it is async method - result is returned via callback function

iota.api.getNewAddress(MySeed,
    { "index": 0, "total": 3, "security": 2 },
    function (error, success) {
        if (error) {
            console.log("Error occured: %s", error);
        } else {
            console.log();
            console.log(success); //returned addresses are printed out
        }        
    });
