been seeing some numerous post about learning JavaScript, so i decided to create a single thread again because most of my JavaScript thread always assumes everyone is a js coder, so i will start from the basic, sometimes i might copy some parts from the web, so plagiarism-intent is activated and sadly because NL has no Syntax Highlighter, i might use JSFiddle and some other javaScript tools online, JavaScript has massively changed from alert box, its now in Servers, and ways to write them are now more complex, and so much tools available at our disposal. buckle up if you intend to learn because it will be heavy but worth the ride.

So before i start i will state the two Chapters ( as stated i will pull some information from other sources)

1. Overview of javaScript
2. JavaScript Object Data Type

Tools Required for this

1. Chrome + Web Developer(already Installed) same with Safari
2. Firefox (Firebug + autoComplete)extension
3. IE( i won't advise it but it can work)

don't attempt to start without getting the necessary tools for firebug go to get.firebug.com

From Mozilla Developer Network
Overview
JavaScript is an object oriented dynamic language; it has types and operators, core objects, and methods. Its syntax comes from the Java and C languages, so many structures from those languages apply to JavaScript as well. One of the key differences is that JavaScript does not have classes; instead, the class functionality is accomplished by object prototypes. The other main difference is that functions are objects, giving functions the capacity to hold executable code and be passed around like any other object.

Let's start off by looking at the building block of any language: the types. JavaScript programs manipulate values, and those values all belong to a type. JavaScript's types are:

Numbers
Strings
Booleans
Functions
Objects

One love bros , many thanks in anticipation

Pc guru, please go on, i am loving this, and dont get discourage by other gurus in the forum, please finish this tutorial. Thank you.

The Number JavaScript object is a wrapper object allowing you to work with numerical values. A Number object is created using the Number() constructor.

Because the Number is a bit complicated there is a link that explains the Number Object, JavaScript has no concept of integer, so for detailed operations involving numbers, you will need to get acquainted with the Number, the Number just as every Object has its properties and functions, the next is "String"

good morning to u all. hope u had a great night. pls guru's in d building do you have or knows anyone that have an account with sedo.com. a client contacted me to help buy back their domain. I have tried to register on the website so that I can make a bid twice buh
account is yet to be approved. pls sir I will appreciate your effort. Regard.

Sorry because of Induction and school Registration,i didn't have time for this,

Strings

Strings in JavaScript are sequences of characters. More accurately, they're sequences of Unicode characters, with each character represented by a 16-bit number. This should be welcome news to anyone who has had to deal with internationalisation.

If you want to represent a single character, you just use a string of length 1.

Now if you are familiar with C++ you will know there are Char 'a' and Char[3] 'Sexy' and String "Hello", JavaScript unlike C++ treats Chars and Strings as the same, and though String is an Object,the string function has so many useful functions such as length,search,replace,charAt. Strings are actually simple to use, however when having multiline strings, you will need to break them into smaller fragments unlike PHP JavaScript will not take whitespacing likely

var htmlSTring = "<div>
  This is a string.
</div>";

Am developing a website and i need a comprehensive list of all the towns in the world , their corresponding states and country. Please is there anybody out there that can be of help?

i don't want to sound like a mean person, but this thread is meant for JS Tutorial pls create a thread for that or http://www./169274473187646/doc/235139146601178/ pls do not derail this thread thanks

PC Guru, tanks for ur time. I am a newbie and happen to see ur thread. I love it.

Sorry this thread will be alot slower from next week, i will be having 10000 words projects, developing a game and meeting companies/group meeting so i will try to update at a much free time.

And there are Booleans Objects, now this is a bit tricky because there are the primitive Boolean values true or false and the Boolean Object, you will find yourself making use of the primitive value most of the times, always make sure to never use a Boolean Object to make a comparison, the article below is a very good example of such
http://www.diveintojavascript.com/articles/javascript-boolean-objects-vs-boolean-primitives

Now functions are the bane and most important concept in JavaScript so this is vital i will summarize and refer to links and just hit the main point, in JavaScript Functions are much more different than every other languages, Functions here in JavaScript are actually a "Function Object", now function Object how does that work based on what you know in Java/C++/C# the only language that has similarity with is Python (but pls feel free to research on this), Functions in traditional languages are nothing more than codes and variables kept called in the stack and used when its being called, but in JavaScript functions too are Objects they have properties,and also have functions(no pun intended), infact the beauty of JavaScript is that a function can be overwritten on the run which is not possible in most languages, infact you can write a library that overloads a previous function and run your own function, function is the key to understanding JavaScript.

Sorry bros got a game to develop for school and 12000 words projects and a web app project. foreign skool ain't easy am back to add some more ish

Another Complicated issue is JS is the issue of "this", this usually confuses alot of JS Dev sadly, as much as i know it, its really hard for me to explain this(no pun intended) without touching context and Global objects, so a link that discusses it will be posted here, the only hint or advice i can say is that Function has two method of changing context and they are apply and call.

PC GURU i take God beg you take this class serious as you got a serious following here ready to learn

my priorities are my studies and work, its the free time i use to spend here, but others are free to add to it, it wud be doing me a favour

Now Functions in JavaScript are a Objects and can be passed around like variables,you can even create a function that returns a function and dynamically attach properties to it, which makes JS beautiful, back in the good old days when there was a function to extend classes, a function was created and you iterate over the source properties and copy to the destination function easily. Function is the key concept to knowing JavaScript, yes there are tons of frameworks everyday but without the adequate knowledge of functions you will find using frameworks like dojo hard to use and also difficult to debug jquery. JavaScript for Web Developers by Nicholas Zakas is amazing and there is the JavaScript Enlightenment which is a free pdf to download.
www.javascriptenlightenment.com/JavaScript_Enlightenment.pdf

Infact this Book JavaScript Enlightenment is superb we will review the book, by now i assume you shouldn't expect this thread to teach everything, the journey is meant for you to read and research and practice. it will be fun

pc guru, please can you give us links to good javascript tutorial website.. From beginners throught to advanced. I have seen two sha! Quirksmode.org and Mozilla developer network if am not mistaken. And you can also tell us what you will talk about after you are through with one topic in javascript to make things easier, faster and so that we can ask question concerning them... Thank you.......

JavaScript Garden is the fastest and easier in my opinion, but Mozilla Developer Network is another. I'll try to do that.

pc guru: JavaScript Garden is the fastest and easier in my opinion, but Mozilla Developer Network is another. I'll try to do that.

when i searched for javascript garden on google.com, it shows a www.github.com of javascript garden. Or am i getting it wrong? Give the full address nah.

sorry for the break, class work doubled, plus i had some minor issue with school and also the police, just happened to be at the wrong place and time, anyway will be copying from the book JavaScript for Enlightened i assumed any serious JS Dev would have download and gone over it.

looking for a HTML5 Developer with jQuery and Git Knowledge,its for a company, Konga thanx
