Difference between JavaScript and AngularJS

JavaScript is a scripting language that is used to generate dynamic HTML pages with interactive effects on a webpage that runs in the web browser of the client. On the other hand, Angular JS is a framework that is built on JavaScript and adds new functionalities to HTML. Its primary purpose is to facilitate the creation of dynamic and single-page web applications (SPAs).

In this article, we are going to highlight the differences between Angular JS and JavaScript. Let's start with a basic understanding of JavaScript and AngularJS.

What is JavaScript?

JavaScript is a simple programming language that is most frequently utilised as a part of webpages. JavaScript implementations on webpages make it possible for client−side scripts to interact with the user and produce dynamic websites. It is a type of programming language that is interpreted and can handle features that are object−oriented.

• The fundamental JavaScript programming language was given a standard form by the ECMA−262 Specification.
• JavaScript is interpreted and therefore very lightweight.
• It is designed for the purpose of developing apps that focus on networks.
• JavaScript complements and is fully incorporated with HTML. It is free to use on several operating systems.

JavaScript Development Tools

One of the most significant advantages of JavaScript is that it does not call for the use of pricey development tools. You may get started with something simple like Notepad as your text editor. Since it is a language that is interpreted inside the environment of a web browser, you won't even need to acquire a compiler to use it.

Many different manufacturers have developed quite helpful JavaScript editing tools in order to make our lives easier. For example, Microsoft FrontPage is a widely used HTML editor. Web developers have access to a variety of JavaScript tools inside FrontPage, which may aid them in the process of creating dynamic websites.

Utilization of JavaScript

Creating interactive webpages often requires the usage of JavaScript. Its primary applications are:

• Client-side validation,
• Dynamic drop-down menus,
• Including the date and the time,
• Putting up new windows and dialogue boxes as they appear (like an alert dialogue box, confirm dialogue box, and prompt dialogue box),
• Including things like clocks, etc.

Here's a simple JavaScript code:

<script>  
   document.write("This text in to JavaScript");  
</script>

What is AngularJS?

The AngularJS Framework is an extremely strong version of JavaScript. Single Page Application (SPA) projects use Angular JS. It enhances the responsiveness of HTML DOM to user actions and adds new properties that increase HTML DOM's capabilities.

AngularJS is a free and open−source software framework that is used by thousands of developers all over the globe. It is distributed with the Apache licence version 2.0 attached to it.

If one already has a fundamental understanding of JavaScript, then learning AngularJS is a breeze.

General Features of Angular JS

The following is a list of the general properties that AngularJS possesses:

• With the help of the AngularJS framework, you can make Rich Internet Applications (RIAs) that work well.
• Developers have the option, thanks to AngularJS, of writing client−side apps in JavaScript in a manner that is cleanly Model View Controller (MVC).
• Applications that are created in AngularJS are compatible with a wide variety of browsers. AngularJS handles JavaScript code in a manner that is automatically appropriate for each browser.
• AngularJS is a web development framework that is open source, does not cost anything to use, and is used by thousands of developers all over the globe. It is licenced under version 2.0 of the Apache General Public License.

Benefits of Using AngularJS

The benefits of using AngularJS are as follows:

• AngularJS makes it possible to make Single Page Applications that are very well organised and easy to keep up.
• It adds the possibility of data binding to HTML. As a result, it provides the user with an experience that is both rich and responsive.
• AngularJS code is unit testable.
• Dependency injection and separation of concerns are two concepts that are used by AngularJS.
• AngularJS offers reusable components.

Overall, AngularJS allows developers to accomplish greater functionality with fewer lines of code.

Drawbacks of Using AngularJS

Even though there are lots of benefits that come with AngularJS, there are still some concerns that need to be addressed.

• Applications created with AngularJS are not secure since the framework only supports JavaScript, which makes them insecure. To keep an application safe, authentication and authorization have to be done on the server.

• Not degradable: If a user of your application disables JavaScript, then nothing other than the default page will be shown.

Difference between JavaScript and AngularJS

The following table highlights the major differences between JavaScript and AngularJS:

Key	JavaScript	AngularJS
Definition	It is an object−oriented scripting language that is used in the process of application development, specifically for mobile and dynamic web platforms.	It is an open−source framework that may be used to create dynamic web applications as well as massive single−page web apps.
Programmed	It uses the C and C++ programming languages to write its interpreters.	The code behind AngularJS is written in JavaScript.
Syntax	Its syntax is far more difficult to understand than that of Angular JS.	Its syntax is simple and easy.
Filters	It doesn't support the filters.	It is possible to use filters with it.
Concept	The principle of dynamic typing serves as its foundation.	Angular JS is an application−building framework that is predicated on the MVC architectural pattern.
Dependency injection	The dependency injection mechanism is not supported by it.	AngularJS supports both data binding as well as dependency injection.

Conclusion

The creation of web apps may be accomplished using either of these two web technologies. Both JavaScript and AngularJS are free and open−source programming languages. AngularJS is an open-source framework based on the MVC approach.

JavaScript is a kind of computer language that may be used to create websites. It can make websites more interactive. It is possible to alter the content on websites in order to check user reaction at the browser end. As a result, it is possible to influence user activity by integrating dynamic content such as drag−and−drop components, sliders, and a great many other things. It is the basis for all JavaScript technologies and is considered to be one of the three basic technologies that make up the World Wide Web.
