JavaScript remains among three key technologies of the present generation World Wide Web frameworks including HTML and CSS. In this article, the reader will be provided with the information about what JavaScript is, the main characteristics of the language, and the main cases of its application and potential disadvantages.
A Brief History of JavaScript
JavaScript is one of the most programmable languages of web that has been developed by Netscape Communications Corporation during early 1990s when the company was working for a new Navigator web browser. Brendan Eich of Netscape communications group was granted the challenge of developing a scripting language that would enable other developers to expand the functionality of a Web page. It was adopted in 1995 and was called LiveScript that due to Java frenzy at that time decision was made to rename it to JavaScript.
The first version of Netscape Navigator 2.0 appeared in 1995 and was enhanced with JavaScript. This was a big step towards future of using themes in the web since it was now possible to design hooks which could generate new web content depending with the kind of input from the user.
Javascript is dynamic and has gradually been implemented into every aspect of the World Wide Web and it is used commonly. However, the appearance of the ECMAScript specification of JavaScript code in 1997 only reinforced its position as the platform of the web.
Key Features of JavaScript
Dynamic Typing: JavaScript is a scripting language and also dynamic language that gives JavaScript some advantages than other separated statically typed languages which are sometime complicate and sometime not ease to used on the other palm it give JavaScript the possible of runtime errors.
Object-Oriented Programming: JavaScript is actually a close relative to OOP, is equipped with class and object, as well as inheritance, polymorphism and other mechanisms. This makes it possible for developers to eliminate repetitive coding but to create pieces in form of modules instead.
Asynchronous Programming: JavaScript is perfect for asynchronous operations which means that the operation works on the same task that would otherwise take a long time before completion, yet other operations within the program are simultaneously functioning. This is most appropriate in the use of web 2.0 based applications, where it is required to request for server and others.
DOM Manipulation: JavaScript communicates with document object model or tree structure of the file that is Structure of the current HTML file. This implies that developers can modify he layout and functionalities of the web page at their own volition.
Cross-Platform Compatibility: Since the current developments in the Web involve JavaScript in its speeches, one can refer it to as belonging rather to the group of portable programming languages. This is why you can run any JavaScript code on any device, at any platform you wish to develop your websites at.
Advantages of JavaScript
Ease of Use: By and large, JavaScript is not complicated for developers to learn, or use, let alone master if at all the developer has prior knowledge on the other programming languages.
Versatility: JavaScript is fully adjustable and can be applied at each level from client-side programming to server-side scripting.
Large Community: Because is one of the most used languages and has a huge and active community of developers, much useful information and help can be found.
Performance: JavaScript has grown in optimization; current web browsers are fast enough to execute a JavaScript code.
Frameworks and Libraries: Some JavaScript frameworks and libraries out there are React, Angular and Vue. js.
Disadvantages of JavaScript
Security Risks: JavaScript codes are vulnerable to various kinds of attacks for example cross-site scripting attacks (XSS) and injection attacks.
Browser Compatibility Issues: Most of the new version of browsers support JavaScript to some reasonable degree but there might be differences between different browsers or between different versions of the same browser.
Performance Limitations: At times, JavaScript is not as efficient in some areas as the other languages because this language is slow in computation.
JavaScript Daily Usage
Client-Side Scripting: JavaScript is mostly used in client-side scripting because it enables the formation of web pages that can be modified by input from the client.
Server-Side Development: Node js is one of the most-employed channels by which developers can use javascript to code in the server-side that can help to build scalable apps and also has high performance.
Mobile App Development: The area of application of JavaScript is the use of frameworks, including React Native and Ionic for the creation of mobile applications with the help of given language.
Game Development: Web Games and other related interactive solutions can be created with the help of JavaScript.
Desktop Applications: Electron is a technology through which a developer can build an application for various platforms, including the development of desktop applications using JavaScript, HTML, CSS.
Summary
JavaScript is an interpreted, multimedia, and dynamic language used for programming in the Web Development Technologies. This idea has such benefits as dynamic typing, OOP characteristics in the code, synchronizing options, and the ability to work with DOM. However, something as weak as security issues, problem with cross-browser support, etc are present in JC, ED But JS has quite strong sides that outweigh its shortcomings a lot of times. JavaScript is most likely to stay one of the main technologies at the WWWW during several years in the future considering such further development trends.
