JavaScript vs Angular JS

JavaScript vs Angular JSUndoubtedly, JavaScript is one of the most popular programming languages in the world. Millions of developers use JavaScript to create web applications and even mobile applications. But what about Angular JS? Angular JS is a JavaScript framework that was created by Google. We primarily use it for developing front-end and creating single-page web applications. Therefore, a question comes in the mind, which one should we use? JavaScript or Angular JS? In this article ‘JavaScript vs Angular JS’, we will compare these two technologies and see their differences. Once you go through the complete article, you will also be able to make a decision which one to use as per your requirement.

Needless to say, both technologies are very popular in terms of utilization and acceptance in the industry. Hence, it becomes essential for every developer to know the detailed description and the differences between both the technologies. Let’s start discussing our article ‘JavaScript vs Angular JS’ and its related concepts.

What Is JavaScript?

JavaScript is a scripting language that offers us to implement complicated features on user interface pages. We may manipulate multimedia, animate graphics, and create information that updates dynamically. Building dynamic HTML pages with interactive effects on a website requires using JavaScript. JavaScript is commonly employed in the creation of mobile applications and video games.

It is an interpreted scripting language, and a web browser is the only application to run its code. To run the code outside of a browser, we might use Node.js. Moreover, people in the industry also call it a browser’s language. We can utilize it in server-side and client-side programming. Initially released in 1995 and invented by Brendan Eich of Netscape. Before becoming known as JavaScript, the language was first called Live Script. The C programming language greatly influences the syntax of JavaScript. The extension of JavaScript file is ‘.js’.

Features of JavaScript

JavaScript has several features. Here are a few of them:

  • JavaScript was created with DOM manipulation in mind. Before JS, most websites were static. JS allows for the creation of interactive, dynamic web pages.
  • JavaScript objects are functions. They may be used as arguments in other functions and have the same characteristics and methods as other objects.
  • A compiler is not necessary for JavaScript to compile.
  • JavaScript can handle dates and times easily.

What Is Angular JS?

Angular JS is a JavaScript-based open-source front-end web application framework mainly maintained by Google. It has excellent features and support as well. The Angular team at Google initially released it in 2010. It’s a framework that’s always evolving and growing to incorporate better ways to make web applications. It is very suitable for working with MVC based application. MVC (Model view controller) is the primary application development framework that supports dependency injection and data binding functionalities.

Features of Angular JS

Angular JS has a variety of features. Here are a few of them:

Time-saving: Working with modules in AngularJS enables code reuse and time savings.

Simple to use: As Angular JS internally uses HTML, CSS, and JavaScript languages, it becomes simple to use.

Always ready to use: When AngularJS is prepared to use a template, it provides the plain HTML template to the DOM and then to the AngularJS compiler. Angular JS is primarily made of plain HTML. Once it has been through the templates, they are prepared for use.

JavaScript vs Angular JS

JavaScript is a simple, object-oriented programming language that creates interactive, dynamic HTML pages in the client’s web browser. It is a client-side scripting language that adds dynamic, interactive effects to websites. In contrast, Angular JS is a JavaScript-based framework that adds new functionalities to HTML. Its primary intent is to create dynamic and single-page web applications (SPAs). This article will discuss the distinctions between JavaScript and Angular JS. We will first learn some basics of JavaScript and Angular JS, and then explore into the detailed discussion of their differences.

JavaScript and Angular JS Basics

JavaScript, a high-level multi-paradigm programming language, focuses on client-side scripting to create dynamic web pages and apps. Additionally, server-side programming can be handled by it. On the other side, AngularJS is a JavaScript web application framework used to create substantial single-page web apps.

The primary function of JavaScript and Angular JS

JavaScript is a well-known web development technology that includes interactive effects into web pages to give them a more dynamic appearance. It modifies the website content to provide dynamic rich web pages without interacting with the server-side browser. A JavaScript utility called Angular JS offers a systematic foundation for creating SPAs from scratch.

JavaScript and Angular JS Programming Model

With JavaScript, developers and programmers may build dynamic web applications that enhance website interactivity by employing client-side and server-side programming techniques. Angular JS, a front-end JavaScript-based framework supports the hard lifting of DOM manipulation, MVC pattern etc.

JavaScript and AngularJS’s simplicity

One of the most potent web development tools used for online power apps in JavaScript. Due to its complexity, it is a flexible programming language that is frequently regarded as one of the most misunderstood languages. The complexity, however, is always in the frameworks and libraries rather than the language itself. The most popular JavaScript framework for building dynamic website elements is Angular JS. It is specifically made to increase simplicity and effectiveness.

Expressions of JavaScript and Angular JS

HTML is linked to application data using JavaScript and AngularJS expressions. Expressions in Angular JS and JavaScript can both contain literals, operators, and variables. Expressions in AngularJS do not support loops, conditionals, or exceptions, although they do in JavaScript expressions. Moreover, Angular JS expressions support filters, they are not supported by JavaScript expressions.

A Comparison of the Two Languages

JavaScript and Angular JS are the two popular programming languages in the user interface handling. Both have pros and cons, so it’s important to choose the right language. Here’s a comparison of the two languages to help you make a decision.

JavaScript is a universal language used for front-end, back-end, and full-stack development. It’s easy to learn and has a large community of developers who can offer support. However, JavaScript can be slow and inefficient, especially compared to Angular JS. Moreover, Angular JS can be challenging to learn if you are new to programming, and it may take some time to get used to its syntax.

On the other hand, Angular JS is a framework designed specifically for building single-page web applications. It’s much faster and more efficient than JavaScript, but it can only be easy to learn if you are familiar with the basic programming concepts. You may choose Angular JS if you need a fast and reliable solution for your project.

Key differences between JavaScript and Angular JS

There are multiple key differences between JavaScript and Angular JS. Here are a few of them:

  • JavaScript is a scripting language for creating online applications that may be used on the server and the client. However, Angular JS focuses on making web apps simple and easy to use.
  • Fixing systemic issues and flaws in JavaScript are quicker. Angular JS takes longer than JavaScript to do the same task.
  • One of the best web development methods for building web applications in JavaScript. On the other hand, the main application of Angular JS has been as a JS framework for creating web applications.
  • JavaScript is used to alter the DOM (Document Object Model). On the other hand, Angular JS uses many technologies to expand its capabilities.
  • JavaScript does not support dependency injection, whereas Angular JS supports both dependency injection and data binding. JavaScript code runs quickly. However, Angular JS applications frequently may become slow.
  • JavaScript has employed a similar approach for many years. The applications are now lighter and more engaging because Angular JS enhances typescript.
  • An extensive user interface for JavaScript incorporates sliders and other features. Angular JS, on the other hand, is a data-driven framework for building online apps.
  • JavaScript is a strong and sophisticated programming language. On the other hand, Angular JS is a lightweight framework that works well.

Difference between JavaScript and Angular JS

Programming: The interpreters for JavaScript are created using the C and C++ programming languages. JavaScript is the language used to write code in the Angular JS.

Syntax: As compared to Angular JS, the syntax of JavaScript is far more difficult to grasp. It has an easy-to-understand syntax in Angular JS.

Filters: The filters are not supported in JavaScript, while Angular JS supports the use of filters.

MVC Architecture: The dynamic type notion serves as the foundation of JavaScript. The MVC (a framework for building apps) architectural paradigm is the foundation for Angular JS.

Dependency Injection: JavaScript does not support the dependency injection approach. Data binding and dependency injection both are supported by Angular JS.

Web applications can be developed using any of these two web technologies. JavaScript and Angular JS are the two examples of free and open-source programming languages.

Pros and Cons of JavaScript

Web applications are implemented with the help of both the technologies. Moreover,  Angular JS is an open-source framework built on the MVC model, JavaScript is an open-source, object-oriented programming language. JavaScript is a web development language that improves the interaction of websites. By incorporating dynamic content such as drag-and-drop components, sliders, and many others, it is possible to alter the material on websites to validate user feedback at the browser end and influence user behavior. It is one of the three pillars of the World Wide Web and the base for all JavaScript technologies.

On the other side, Angular JS is a JavaScript-based open-source framework specializing in creating large single-page applications. The MVC architecture serves as its foundation. Thanks to this data-driven methodology, web applications can now use a more extensive HTML library. It is an architecture for the future that will enable enormous data requirements to be met without Models needing to be updated.


Which is superior,  AngularJS or JavaScript?

JavaScript is known for an extensive user interface. It offers sliders and other modern features. Angular JS, on the other hand, is a data-driven framework for building web applications. JavaScript is a strong and sophisticated programming language. On the other side, Angular JS is a lightweight framework.

Can JavaScript be used with Angular?

Yes, it is obvious. Install the JavaScript library using npm, then look for its type of the declaration file to utilize it in an Angular project. If the type of declaration file is not included in the source code, get it from @types/library-name>. Start utilizing the library by importing it into your component.

Is Angular JS a good career choice?

The use of Angular can help you acquire the best jobs. An angular-based web development profession is prosperous. Additionally, big global corporations use it, making angular a wonderful career choice.

Should I learn JavaScript or Angular?

Many suggest that before learning Angular, you should have a basic understanding of JavaScript once. To put it modestly, the task will be 100 times tougher if you don’t know JavaScript. Hence, once you have a basic understanding of JavaScript, you can go with Angular.

What is TypeScript, and how does it relate to Angular and JavaScript?

TypeScript is a statically typed superset of JavaScript developed by Microsoft. It extends JavaScript by adding static typing to the language, allowing developers to define and enforce data types for variables. TypeScript also introduces features from object-oriented programming languages, making it a more structured and scalable option for large-scale application development.

Angular, on the other hand, is a web application framework that is built using TypeScript, making TypeScript the preferred language for Angular development. The combination of TypeScript and Angular offers developers a powerful and structured approach in building scalable and maintainable web applications.
