What is JavaScript?
JavaSript is a programming/ scripting language that enables you to create dynamic webpages and applications. It works by using the browser’s engine so that your webpage can communicate with external programs or databases. This allows for interactivity and customization on web pages, which makes it an essential tool in developing user-friendly websites.
History of JavaScript
Javascript was created in the late 1990s to make websites more interactive. It was first used on the web pages of Netscape, and then Mozilla later incorporated it into their browser. Javascript quickly became popular because it allowed developers to write code in a simple, easy-to-read language that was also cross-platform compatible.
Application of JavaScript
- JavaScript is used to create dynamic web pages that are interactive.
- It is also used for performing user authentication and managing sessions.
- It enables you to create custom forms and send requests to web servers.
- JavaScript is used in many applications, including front-end development, e-commerce, and mobile apps.
Advantages and Limitation of JavaScript
JS is a powerful programming language that can create sophisticated web applications.
- It is versatile and can be used for different purposes, such as front-end development, back-end development, data science, game development, mobile application and more.
- It has a well-defined syntax that is easy to understand.
- It supports object-oriented programming and versatile data structures.
- JS is widely used in the development of websites and web applications.
Developers need to be aware of certain limitations to the JavaScript language. These include:
- JavaScript is not Turing-complete, meaning it cannot perform specific tasks that other programming languages can.
- It is impossible to statically typeset JavaScript code, which means that it can be vulnerable to errors if it is not typeset correctly.
- Multi-threading and multiprocessor features are not supported in JavaScript.
Client-Side JavaScript & Server-Side JavaScript
Client-side javascript refers to the code run on a user’s computer, while server-side javascript refers to the code executed on the server. Client-side development scripts are generally easier to modify and often faster because a web browser does not process them. However, server-side scripts can be more reliable because they are performed within an application context rather than in queries sent between browsers.
Features of JavaScript
It is a structured programming language. JavaScript refers to the C programming language’s syntax and structure.
- JavaScript is a widely used programming language that is often used in web development.
- It is a high-level, general purpose, interpreted, cross-platform language.
- It supports object-oriented programming, and most importantly, it is versatile and can be used in many different contexts.
- It can be used to create dynamic web pages, dynamic content, and interactive applications.
- It runs on all popular browsers, including IE, Chrome, Firefox, and Opera.
JavaScript Development Tools
Many Javascript development tools are available, but some of the most popular include Eclipse, visual studio, and webstorm.
- Eclipse: Eclipse is a development tool enabling you to develop and test web applications using Java. Additionally, Eclipse provides tools for managing projects, code reviews, and testing. It also has an integrated debugger that makes it easy to track down bugs in your code.
- Visual Studio: A visual Studio is a development tool that can create web applications using Javascript. Web application developers use Visual Studio to design, build, and test their applications using the latest technology stack.
- Webstorm: Webstorm is a Javascript development tool that helps you to rapidly develop robust, well-tested web applications. It features an intuitive stepped outline editor, fly-by-wire code navigation system, and rich context menu support for quickly adding files and commands to your project. Webstorm also contains extensive pluggable modules that give you complete control over the functionality of the IDE.

FAQs
Why JavaScript is known as a lightweight programming language?
JavaScript is a lightweight programming language because it runs quickly on web browsers, making it ideal for creating interactive websites. It also has many built-in functions that make software development more efficient.
Is JavaScript compiled or interpreted or both?
JavaScript is both compiled and interpreted. This means that the code you write is turned into a machine-usable form before it is run, but it can still be executed on the server side or in a browser.
Conclusion
In this article, Introduction to JavaScript, you have learned all the basics of JavaScript. It has long been one of the most widely used languages on the web today because it enables you to build complex websites without needing to write a single line of code. Great scriptwriting can make or break your site’s success! If you want to become an expert in scriptwriting within no time, keep reading articles related to this topic and try new techniques too.
