I loved your tutorial on the twitter bot, and can't wait for the one on deploying it on a server :D

How about putting the node.js twitter bot onto a server so that it can run forever!

It would be awesome to have some videos explaining how to use API that requires oAuth authentication in Processing and P5.js.

Is there a way for you to put videos on youtube for these examples:
VIDEO 1

//Question 2 Create a function that takes a string as its input and returns the number of vowels that appear in the string.

var str = "clarissa";

function someStr(str){
var i;
var vLent = str.length;
var cntArr = 0;
var ch;
for (i=0; i<vLent; i++){
ch = str.charAt(i).toUpperCase();
if ((ch == 'A') || (ch == 'E') || (ch == 'I') || (ch == 'O') || (ch == 'U')) {
cntArr++;
}
} return cntArr;
}

//to call function
someStr(str)


VIDEO 2

// Write a function that takes an array of numbers and returns an array of all the odd numbers in that array.
var arr = [5,10,15,20,25,30,25,40];

function myKids(array) {
var odds = []; // array that will track all odd numbers

// Loop through all items in the array
for (var i = 0; i < array.length; i++) {
    // Find odd numbers
    if (array[i] % 2 !== 0) {
        odds.push(array[i]);
    }
}

return odds;

}


VIDEO 3

// Constructor Function Example
function Family(mother, father,baby) {
this.first = mother;
this.last = father;
this.age = baby;
}

Family.prototype.sayHello = function() { console.log('HELLO!'); }
Family.prototype.sayBye = function() { console.log("Good Bye!"); }

var family1 = new Family("Peter", "Anna", "Thomoas");


VIDEO 4

var sum = 0;
for (var key in citypopulus) {
if (typeof cityPopulus[key] !== 'function') {
sum += citypopulus[key];
}
}

var cityPopulus= {
'northWard': 30000,
'southWard': 1000,
'centralWard': 1000,
'eastWard': 5000,
'westWard': 4000,
talkNewark: function() { console.log('Newark! Newark!'); }
};

Not sure if this fits in small topics, but could you discuss how to utilize promises, too?

I can't wait for you to discuss/teach these other topics! So much good stuff to come!

Daniel, is socket.io (realtime engine) with p5js a topic you would be interested in to add to the list?

I'm working on a web based project with four MP3. It's takes several seconds to load and the "Loading..." message with a CSS image it's not enough. I want to add a percentage with the progress. How can we do a full feature preloader screen in P5JS? It's possible or we need to use another tool and run the sketch with a callback? Thanks!!!

@colormono

Another idea for small topics. Compile a P5JS into a native mobile app.

It would be great if you'd have the links to the videos behind the topics you already made a video on (or embed them as links if possible) :) Thanks for the great work!

ArrayList, HashMap, IntDict, FloatDict etc... in Processing vs P5js

Can you do video/s on p5.dimensions ?
