A few days ago I signed up for #CNC2018 blog more quest and for the I'll be publishing this article.
Today I shall be writing about the sweet ' sour programming language JavaScript. To start off let me tell you why I chose this first of all I did a twitter poll then I did some research in which I found that on numerous blogs, Facebook groups, tweets etc. People often have asked that "can I learn JavaScript before learning any other programming language? Or JavaScript is so hard! Or JavaScript is useless" .
Each comment compare do the other sounds ridiculous so I made myself a pledge that I will spread out the holy language that is JavaScript.
Javascript
JavaScript often abbreviated as JS, is a high-level, dynamic, weakly typed, prototype-based, multi-paradigm, and interpretedprogramming language. Alongside HTML and CSS, JavaScript is one of the three core technologies of World Wide Webcontent production. It is used to make webpages interactive and provide online programs, including video games. The majority of websitesemploy it, and all modern web browsers support it without the need for plug-ins by means of a built-in JavaScript engine. Each of the many JavaScript engines represent a different implementation of JavaScript, all based on the ECMAScript specification, with some engines not supporting the spec fully, and with many engines supporting additional features beyond ECMA.
1. Animation
$fx() $fx() is a lightweight library for animating HTML objects. Using it, you can alter any CSS property within a given timeline. For complicated animations, you can combine effects, group them to chains and run them in parallel. And you can set different callbacks at every step to customize it further.
JSTweener A tweening library for JavaScript. Its API is similar to the famous ActionScript tweening engine Tweener. You can mention the time of the animation, define the transition effects and delays. At almost any point (like onStart, onComplete, onUpdate) you can fire new events.
Facebook Animation A powerful library for creating customizable CSS-based animations. With a line or two in Facebook Animation, you can improve the UI. The syntax is identical to the FBJS version (the library used in Facebook applications) and once learned, it is an asset for creating Facebook applications.
FX A lightweight library, with a YUI-like syntax, FX can create a tween for almost any CSS property. It supports color and scroll animations. Designing the “to” and “from” values of any object/property is enough.

3. Visualization And Image Effects
JS charts JS charts supports bar charts, pie charts and simple line graphs. It offers nice usability by simply inserting the library onto Web pages and calling the data from an XML file or a JavaScript array. Charts are created as PNG files and the library is compatible with all the major browsers.
Canvas 3D JS Library (C3DL) C3DL makes writing 3D applications easy. It provides a set of math, scene and 3D object classes to make the canvas more accessible to developers who want to develop 3D content in a browser but not have to deal in depth with the 3D math needed to make it work.
Processing.js This is a JavaScript port to the Processing language (a language for programming images, animation and interactions). The library is feature-rich for creating 2D outputs. It provides methods for shape/image drawing, color manipulation, fonts, objects, math functions and more.
Raphaël An amazing library that simplifies working with vector graphics on the Web. Raphaël uses SVG and VML for creating graphics that can be modified and event handlers that can be attached to them. The library is feature-rich in functions, including rotation, animation, scaling and drawing curves, rectangles and circles.
ImageFX This is a JavaScript library for adding effects to images, like blur, sharpen, emboss, lighten and more. ImageFX uses canvas element for creating the effects. It is compatible with all major browsers (there is a compatibility chart on the script’s page). The library is so easy to use. Simply inserting the .js file in the Web page and calling a one-line function is enough.
Pixastic Pixastic uses the HTML5 canvas element, which enables accessing raw pixel data. The effects supported include desaturation and grayscale, inverting, flipping, brightness and contrast adjustment, hue and saturation, embossing, blurring and much more. Because the canvas element is relatively new, the library does not have equal support in all browsers yet.
Reflection.js An unobtrusive JavaScript to auto-create reflection effects. The height and opacity of the reflection can be defined. Using it is as easy as adding a “class” to the images. It works in all major browsers and is smaller than 5 KB.
3.Database
Taffy DB A JavaScript library that can be thought as an SQL database in the browser or an advanced “array manager.” It works as a database layer within AJAX’ed Web applications. You can create, read, edit and delete data, use loops, sort them and use advanced queries.
ActiveRecord.js This library supports Google Gears and Chrome, Aptana Jaxer, Adobe AIR, and any platform that supports W3C HTML5 SQL Specification (Webkit and iPhone for now). It makes it easy to work with databases in JavaScript. Using ActiveRecord.js, you can auto-create tables, validate and synchronize data and more.
5. String And Math Functions
Date.js Working with dates are always tricky. So many dots, slashes and formats. Datejs is a stunning library for simple to complex date functions. It can parse dates like: “Next thursday”, “+2 years” and all formats like 2009.01.08, 12/6/2001 etc.
Sylvester This is a JavaScript library for doing vector and matrix math easily, without using a lot of loops and getting lost between arrays. It includes classes for modelling vectors and matrices in any number of dimensions and for modelling infinite lines and planes in 3D space.
Pretty Date A smart JavaScript solution for displaying dates within the past month in a prettier and more user-friendly way. It displays dates relative to the current time; for example, “Yesterday,” “3 hours ago,” etc.
XRegExp Regular expressions can be already used in JavaScript with the RegExp object. XRegExp adds more power to RegExp with features that will be part of the browsers of tomorrow (according to proposals for ECMAScript 4 - ES4). Using the library, RegExp objects can be cached and reused, modifiers can be added to existing RegExp objects and more.
JavaScript URL Library A library for handling and manipulating URLs more easily. It is possible to reach every part of a URL as a string and modify it when needed. This URL library is very new but already works as mentioned.
It is maintained by Facebook, Instagram and a community of individual developers and corporations.
React allows developers to create large web-applications that use data and can change over time without reloading the page. It aims primarily to provide speed, simplicity, and scalability. React processes only user interfaces in applications. This corresponds to View in the Model-View-Controller (MVC) pattern, and can be used in combination with other JavaScript libraries or frameworks in MVC, such as AngularJS.
jQuery's syntax is designed to make it easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications. jQuery also provides capabilities for developers to create plug-ins on top of the JavaScript library. This enables developers to create abstractions for low-level interaction and animation, advanced effects and high-level, themeable widgets.
The point
My point in all of this is yes! you can learn Js with zero knowledge of any other programming language, also it's freakin' easy to learn I learned it in just two weeks!!
Where to learn Js? here you go two free resouces from where you can learn freecodecamp, codecademy
All you need is a computer/laptop/tablet with an internet connection ! no need to buy expensive computers just do it
In this task all you have to do is delete your <h1>Hello World</h1> tags from the editor leaving
<h2>CatPhotoApp</h2>
<p>Kitty ipsum dolor</p>
untouched.
Click on run tests or press Ctrl + enter.
Now moving on to the next task .
Change the Color of Text
In this task we will be changing the color of our h2 element by changing the style we have to add style ="color: red" to your h2 tag like this
<h2 style="color: red">CatPhotoApp</h2>
<p>Kitty ipsum dolor</p>
Click on run tests or press Ctrl + enter.
Now moving on to the next task .
Use CSS Selectors to Style Elements
CSS stands for Cascading Style Sheets is a style sheet language used for describing the presentation of a document written in a markup language.
There are alot of css properties you can use to change the way your element looks like taking the style example from above
<h2 style="color: red">CatPhotoApp</h2>
by doing this only this tag is effected, if i write another h2 tag nothing will happen to it until i have styled it too that would make my code too long and a bit messy so we use css instead.
Now for that you need to open <style> element on the top of your code like this
<style>
</style>
with css you can select all h2 tags like this
<style>
h2 {
color: red;
}
</style>
Now the given task is to delete your h2 element style attribute and create a css style element like this also this time the color of text should be blue
<style>
h2 {
color: blue;
}
</style>
<h2>CatPhotoApp</h2>
<p>Kitty ipsum dolor</p>
Then click on run test(Ctrl+enter)
3 Tasks Completed!
That's it for now
Comment below to ask and questions related to this and I will be sure to answer it
So this task is pretty simple in this all you have to do is comment out your <h1>Hello World</h1>tags and <p>Hello Paragraph</p>tags
and leave the <h2>CatPhotoApp</h2> tag uncommented
Like this..
<!--
<h1>Hello World</h1>
-->
<h2>CatPhotoApp</h2>
<!--
<p>Hello Paragraph</p>
-->
Click on run tests or press Ctrl + enter.
Now moving on to the next task .
Fill in the Blank with Placeholder Text
It says that web developers usually use lorem ipsum text as place holder text. The 'lorem ipsum text' is randomly scraped from a famous passage by Cicero of Ancient Rome.
But since we are making a CatPhotoApp lets use something called kitty ipsum text
Kitty ipsum dolor sit amet, shed everywhere shed everywhere stretching attack your ankles chase the red dot, hairball run catnip eat the grass sniff.
The task here is simple all you have to do is copy a few words from the paragraph above and paste & replace it between your
<p>Hello Paragraph</p>
Like this
<h1>Hello World</h1>
<h2>CatPhotoApp</h2>
<p>Kitty ipsum dolor</p>
Then click on run test(Ctrl+enter)
2 Tasks Completed!
That's it for now

Cuddling the best thing to do that gives that best feeling to anyone and everyone
it can be done with anyone or anything boy, girl, dog, cat, pillow, blanket
Cuddling is a universal way of showing affection. It doesn’t matter if it is a person, animal, or an object like a teddy bear pillow or blanket, cuddling is definitely the best way to say I care about you, I want to be close to you, and I accept you in my space.
1.Feel-Good Hormone
Oxytocin is a hormone that does everything from making you feel good to helping you feel connected to others. Oxytocin is crucial in the act of cuddling, as you’ll see from its benefits popping up in the list below.
2. Boost the Immune System
The release of oxytocin, this feel-good hormone makes you feel like nothing can hurt you—which is an amazing benefit! It also increases hormones that help fight infection. Basically, you’re boosting your immune system because you’re feeling too good and healthy to get sick.
3. Relieve Pain
Just as it boosts your immune system, cuddling and releasing oxytocin will decrease your pain levels. It’s like whenever your neck hurts, you rub it. Even simple touches like that release enough oxytocin to make you feel better, so imagine the effect cuddling has — a full body contact with another human.
With that said I would you to introduce to my cuddle buddy I can with it whenever I want anger , sad or just lonely my cuddle pillow is always there.
In the next few challenges you will be making a cat photo app using HTML5, CSS and Bootstrap
that will look like this
So buckle up because it's gonna be a fun ride to the end!
In the first task you have to give this app a <h2></h2> element tags
This element tells the browser about the structure of your website. h1 elements are often used for main headings, while h2elements are generally used for subheadings. There are also h3, h4, h5 and h6 elements to indicate different and new sections.
Add an h2 tag that says "CatPhotoApp" to create a second HTML element below your "Hello World" h1 element.
If you have read my previous post or done the previous task you might remember the <h1>Hello World</h1> tags here without touches the previous code in the editor you just have to write on the next line <h2>CatPhotoApp</h2> like this
