What is JavaScript
If you're a programming enthusiast, once you see yellow you'll think about programming quickly. Whoever arrived here in search of what we were going to talk about will join the yellow community after you read these lines with us.
Yes, and as no one can tell, yellow brings us straight to java script thinking. But do you have enough information about her? What is different from other programming languages? In this article, we will learn about the areas of use of JavaScript and its most important features. But let's highlight a simplified definition of it so you have the right idea about it.
What is JavaScript
JavaScript is a high-level software language commonly used in website development. Netscape has developed it as a tool to add dynamic and interactive elements to the sites.
JavaScript is heavily influenced by the Java language and is similar in composition to C. It is shown on ECMAScript, which is a software language developed by Sun Microsystems. Over time it replaced a variety of other programming languages to become a standard for browser programming.
JavaScript Evolution
He created Java Brendan Ish in 1995 as Moca while working at Netscape, inspired by Java Java, Skim Scheme, and Self.
This language did not receive attention at the beginning, but in time it became a source of interest for many programmers after adding new techniques and supporting it for the JavaScript language, called JavaScript.
JavaScript Features
- Implemented on the customer side, for example, you can verify any input before sending the order to the server.
- It is a relatively easy language to learn and close to English.
- An independent programming language, not as some believe it is associated with the Java language.
- Provides greater access to browsers.
- Interactive and fast.
- It features rich interfaces and you can pull and drop components to sing your interface with the required items.
- Functional programming language.
JavaScript Restrictions
- Security issues: Since most code is implemented on a user's computer, it can sometimes be exploited for harmful purposes, which requires many people to disable it.
- Do not allow files to be read or written by the client.
- They cannot be used in network applications as there is no appropriate support for this.
- Multi-threaded implementation does not support multithreading, a technology in which implementation takes place in several tracks at the same time on the same processor.
- The JavaScript display varies between different browsers and search engines causing inconsistencies in interface and functionality at times.
Difference between JavaScript and JavaScript
The JavaScript name must make us believe that JavaScript is associated with JavaScript. Although both are based on the C language and are used in web applications by the client, in the following lines we will explain some of the differences between them:
We cannot deny the fact that both Java and JavaScript are programming languages used to develop different apps or features of internet pages, but their code is different from the other.
The greatest difference is the type of application used; Java apps run either from the desktop or through the web page and are independent software and usually open a separate software window. If you don't install Java, you won't be able to run their apps on your device. While JavaScript is usually included in all modern browsers, you will be able to easily use it when uploading a web page. Through JavaScript, different apps can be created on the web page itself, as you can also develop and work on video games in the browser window.
JavaScript is usually based on calculations and logical thinking and largely works on server programming. JavaScript focuses its work on the client side. Which makes JavaScript faster.
While Java can be used to develop large software, it often requires significant memory space that can slowly cause computer work or slow down the work of another program. In contrast, JavaScript operates with small memory space, so it is widely used on many web pages due to low memory requirements and the ability to provide many unique features.
Uses of JavaScript
1. Website Development
JavaScript is a programming language used to create web pages and is a stand-alone language developed in Netscape. It makes the web page dynamic and adds special effects on pages such as scrolling, playing, and many other things and is mostly used by all websites and supports opening PDF documents, running UI elements, supporting flash applications, etc. It can also upload content into a document whenever the user requests it without reloading the entire page.
2. Web Software
When a user explores Google Maps on a computer they only need to click on the mouse and pull it or Fallat and each detailed view can be seen in one click this is possible because of JavaScript language and JavaScript uses APIs that provide additional powers for the code.
3. Presentations
JavaScript offers the ability to create presentations. It offers RevealJS and BespokeJS libraries to build a web-based chipset. Reveal.js creates some of the most beautiful and interactive formations using HTML and you can easily insert overlapping slides even if you are not very familiar with JavaScript programming language, you can easily create an online site.
These presentations have been improved so that they work great with mobile devices, phones, and tablets and JavaScript also provides different transmission patterns, themes, and chip backgrounds and supports all CSS formats. It also provides the Bespoke.js plugin with a variety of features. They include responsive sizing, moving dot code lists, and highlighting the wholesale build of code examples.
4. Server Applications
Node JS is built in Chrome to build fast and scalable apps. It uses efficient, lightweight apps that are distributed to server-assisted systems, and JavaScript is used to handle HTTP requests and create content.
5. Games
Not only websites but JavaScript also helps create games for leisure time. The combination of JavaScript and HTML5 is common in game development and provides a dedicated library that provides simple solutions to work with rich graphics. It also provides a familiar API for all flash developers with a hierarchical display menu. The user can create a stage and the library also contains dot images.
6. Art
Using HTML5 to draw JavaScript graphics on a web page has become easier than before as all 2D and 3D formats can be painted easily and this has opened the browser as a new medium for all different digital art projects and the canvas has no limits and no content and thus allows the user to creativity in the drawing.
7. Smart Watch Applications
Javascript is used in all possible devices and applications and JavaScript provides Pebble JS library which is used in smartwatch applications where using Pebbles enables any JavaScript developer to create a smartwatch app.
8. Mobile Apps
The most important thing JavaScript users can do is create applications for mobile phones running ios and Android
PhoneGap is the framework that enables it. Recently also React Native that serves this purpose and is the main player in changes and deployments across platforms so Javascript can be used to spread and download the respective apps across different environments.
9. Flying robots
Yes, even this area did not leave JavaScript unchanged. Using Node Js the user can program a flying robot.
