Hellos Guys , I am ' Garry ' an Machine learner , Deep Learner , Developer . Do you want to know about the Java script with my own tips then keep reading.
What is JavaScript
JavaScript is a high level language in the programming language family (like Python) that is used to communicate with a server. It is widely used for general purpose desktop application development and to interact with the World Wide Web . ReactJS JavaScript is the only language to make the list of 20 most popular web languages in the world. It is a key part of modern web development and is used by many companies like Airbnb and Facebook. The reason behind JavaScript's popularity is that it is used to build websites that run efficiently on the huge amount of computer resources at our disposal. Why is JavaScript so Popular? It can be easily compiled, which means it is perfect for rapid prototyping.
JavaScript Misconceptions
Many of the people think that JavaScript is a simple language. They think that for a simple script, all you need is a few lines of code. This is not true. It's amazing how many people think that for any code, you only need a few lines of code. Yes, you can do a lot with a few lines of code but it is not true for all. Now let me explain with an example. Suppose you want to create a simple script that will go back and forth with a string and change it from inside a loop, right? Now say you want to say that if 'a' is inside a loop and you want to change it to 'b' then put this code setTimeout(function() { console.log( 'a' + 'b' ); }, 1000 ); As you can see, all you need is few lines of code to make a simple code. But that's not true for all.
JavaScript Variables
An object can have many values, but it can only contain a single value. This is not different in JavaScript ,so a variable is an object and you can have as many objects as you want in the same scope. As we need to assign a value to each variable, we need to define its type. So we have to pass parameters for each variable. JavaScript Expression Now lets us create a variable with an expression. JavaScript (1 + 2) // 1 + 2. Note you have to type 1 + 2. Which is an expression and they accept both floating point numbers and numbers .
JavaScript Operators
This is a cool Java script tutorial that will help you understand the most used JavaScript operators in one place. JavaScript Queries Learn JavaScript as you would a SQL script. JavaScript Playground Play and manipulate with the live DOM and functions. JavaScript Theming Using the styles in HTML to style your JavaScript code JavaScript Shopping List Learn how to manage list, assign categories and progress tracking. JavaScript Dynamic Events Learn how to use dynamic events to callbacks. JavaScript Movie Maker Show scenes, add transitions and control the playback speed of movie. JavaScript TinyMCE & jQuery TinyMCE 4 is a minimalistic JavaScript library that replaces a stock jQuery script. JavaScript Game A cool game to learn the JavaScript basics.
JavaScript Conditional Statements
These statements will be so cool to you. I am teaching you the skills with latest JavaScript code that helps you with breaking the code pattern. I will introduce them one by one that helps you to make better and less errors. JavaScript Functions You can create simple functions with just one or two lines. Sometimes they even come with three or four lines. They also give a chance to you to create single line code to perform various operation with the help of only few lines. Using Different Forms Of Arguments Sometimes you have to pass more than three values with only one or two arguments. The combination of all three arguments can have different operation results. JavaScript Array Refresher When you want to create an Array with more than one data object.
JavaScript Loops
JavaScript loops are the perfect tool for control flow. It's helpful in debugging an application. It is also a way to allow the application to handle time. It provides you with multiple branches. This tool will help in creating a complex, robust and reusable scripts. JavaScript Is an Inheritance Language JavaScript is an object oriented language with inheritance. You can write your code as if the world were an island. This will help in reducing the chance of bugs that may happen.

JavaScript Basics The power of JavaScript lies in the fact that you can reach the web from any device.
JavaScript Objects
JavaScript Objects are more like Fragments , Elements or even Chunks of DOM Tree. They can be accessed by the DOM Node. These can be passed and accessed like Objects , Array and objects, instanceof properties, { } . Let's see in this code below is the button class or button element and it's state. It has a clicked , passed as a parameter and not ready . class Button extends
React.Component { render() { return ( this.setState({ 'value': 'do not have any form fields' })}/> ); } }
var Button = React.createClass({ render: function() { var id, value; this.setState({ 'id': id, 'value': value }); return ( {id} ); } });
ReactDOM.render( , document.
JavaScript Functions
To understand the function you should know how it works. I will give you one example: function parent(x, y) { return x*y; } Parent(5, 5); And the same example with extra function and value. parent(5, [5], 10); A parent function is declared by this statement: Parent(value) { return value; } You can find parent function in almost all the javascript tutorials. But usually it will return a String and returns nothing or not, if nothing is passed. But in this example parent will return a String and it will have access to a value as 5 . That is why parent function returns a String . The first property of the parent function is value . That is the function with result property and value inside.
JavaScript Events
You can easily trigger a JavaScript Event. Let's consider the Event for JQuery which is GET. What do you need to do to trigger the event to change the content of a page? The first thing that you need to know is that you can't trigger a JQuery event without the proper name and that this name can't be more than 31 characters long. So, to trigger the event without a name that has at least 31 characters and to change the content of a page, you need to use the XMLHTTPRequest API and the id. The id is the unique ID that belongs to a JQuery event. If you go to the URL http://localhost:3000/, you can see how to do it in a simple- example-java.net command: How To Create A Script Using JQuery For Request Generate a script using the ID="[String]()" Event
