JavaScript is a compact, object-oriented scripting language that enables the creation of dynamic HTML pages featuring interactive effects, which operate within the user's web browser. As a client-side scripting language, it enhances web pages by adding interactive elements that contribute to a more dynamic experience. Conversely, AngularJS is a framework built on JavaScript that enhances HTML by introducing additional capabilities. Its primary purpose is to facilitate the development of dynamic web applications, particularly single-page applications (SPAs). In this article, we will explore the distinctions between JavaScript and AngularJS. However, prior to delving into those differences, we will first examine both JavaScript and AngularJS.
What is JavaScript?
JavaScript is a lightweight, object-oriented scripting language utilized for creating dynamic HTML pages that incorporate interactive features on a website. This language is also frequently employed in the realms of game development and mobile application creation. As an interpreted scripting language, JavaScript code is executed solely within a web browser environment. However, using Node.js allows us to execute this code outside of the browser context. It is often referred to as the language of the browser, and it is applicable for both client-side and server-side programming tasks. The inception of JavaScript can be credited to Brendan Eich at Netscape, with its first release occurring in 1995. Initially named LiveScript, the language underwent a rebranding to JavaScript. The syntax of JavaScript bears a significant resemblance to that of the C programming language. The file extension associated with JavaScript files is .js.
JavaScript Features
There are various features of JavaScript. Some of them are as follows:
- JavaScript was originally designed for DOM manipulation. Earlier, most websites were static, but with JS, an interactive Web site can be developed.
- Functions are objects in JavaScript. They may have the same properties and methods as other objects and passed as arguments to other functions.
- JavaScript doesn't need a compiler.
- JavaScript may handle date and time.
What is Angular Js?
This is an open-source front-end web development framework that offers impressive capabilities and support. Initially introduced by Google's Angular team in 2010, it is a framework that is consistently evolving and enhancing to provide improved techniques for building web applications. It primarily constructs applications utilizing the model-view-controller (MVC) architecture and incorporates features such as data binding and dependency injection.
AngularJS primarily relies on HTML and JavaScript, which means that there is no requirement to master a different syntax or programming language. It converts static HTML into dynamic HTML, enhancing the functionality of HTML by incorporating built-in attributes and components. Additionally, you can develop custom attributes effortlessly using straightforward JavaScript.
Angular JS features
There are various features of angular JS. Some of them are as follows:
- Time-saving: AngularJS allows us to work with modules that help us to reuse them, saving time and code.
- Easy to work: It is easy to work with Angular JS because it uses JavaScript, HTML, and CSS languages.
- Ready to use a template: AngularJS is mostly plain HTML, and it mostly uses the plain HTML template, which it passes to the DOM and then to the AngularJS compiler. It passes through the templates, and then they're ready to use.
Main differences between the JavaScript and Angular JS
There are various main differences between JavaScript and Angular JS. Some of them are as follows:
- JavaScript is both a server-side and client-side scripting language for building web applications. On the other hand, AngularJS makes web applications quick and straightforward from the start.
- JavaScript takes less time to patch bugs and defects on a wide scale. As compared to JavaScript, AngularJS needs more time to do the same thing.
- JavaScript is one of the most effective web development techniques used for creating web applications. On the other hand, AngularJS has mostly been used as a JS framework for developing web applications.
- JavaScript is a programming language that is used to manipulate the DOM ( Document Object Model). On the other hand, AngularJS extends its capabilities with different technologies.
- JavaScript doesn't support dependency injection. Whereas AngularJS supports both data binding and dependency injection.
- JavaScript code is quick and fast. On the other hand, Angular JS application generally becomes slow.
- JavaScript has been using the same strategy for several years. On the other hand, AngularJS has been enhanced to typescript, making the applications lighter and more interactive.
- JavaScript has an extensive user interface that includes sliders and other features. On the other hand, AngularJS is a data-driven framework that's used to create web applications.
- JavaScript is a powerful and complex programming language. On the other hand, AngularJS is a simple and effective framework.
Head-to-Head comparison between JavaScript and Angular JS
In this section, we will engage in a direct comparison between JavaScript and AngularJS:
| Features | JavaScript | Angular JS |
|---|---|---|
| Definition | It is an object-oriented scripted language that is used to develop mobile and dynamic web applications. | It an open-source framework used to develop dynamic web and large single-page web applications. |
| Developed | Netscape Communications developed it in 1995. | Google mainly developed it in 2010. |
| Syntax | Its syntax is much complex than Angular JS. | Its syntax is simple and easy. |
| Programmed | Its interpreters are written in the C and C++ languages. | It is written in the JavaScript language. |
| Filters | It doesn't support the filters. | It does support filters. |
| Learnability | It isn't very easy to learn. | It is easy to learn if anyone knows the basic knowledge of JavaScript. |
| Concept | It is based on the dynamic typing concept. | Angular JS is based on the concept of the model view controller to build the applications. |
| Dependency injection | It doesn't support the dependency injection. | It supports both data binding and dependency injection. |
Conclusion
Both of these web technologies serve the purpose of developing web applications. JavaScript is a programming language that is both open-source and object-oriented, whereas AngularJS is an open-source framework that follows the MVC (Model-View-Controller) architecture. JavaScript functions as a language for web development, significantly improving the interactivity of websites. It facilitates the manipulation of web content to gather user feedback directly within the browser, thereby influencing user behavior by incorporating dynamic elements such as draggable components, sliders, and various other interactive features. It ranks as one of the three fundamental technologies of the World Wide Web and serves as the backbone for all JavaScript-based technologies.
Conversely, Angular JS is a publicly available framework that focuses on the creation of extensive single-page applications and is implemented using JavaScript. It follows the Model-View-Controller (MVC) architectural pattern. This framework employs a data-centric methodology that allows web applications to utilize a more extensive HTML library. It serves as a forward-looking framework designed to accommodate substantial data needs without the necessity of reloading Models.
