As the internet and technologies continue to change and evolve, how we design applications and code may be required to evolve with it. Angular and AngularJS are both software that allow people to design single-page applications using different types of code language. Understanding how these software work can allow you to excel at your job and develop better applications. In this article, we define what Angular vs. AngularJS is, look at what makes the two software similar, and what makes them different from one another.

Definitions of Angular vs. AngularJS

Listed below are the definitions of Angular vs. AngularJS:


Angular is a Typescript-based program that people can use to create single-page applications. Typescript is a language that was developed by Microsoft and has a more diverse range of functions than JavaScript. It can transfer its information into JavaScript and it's typically used for developing larger applications. Angular has a design that also allows its users to access HTML alongside Typescript. Angular also allows the users to have access to a great set of templates and support that can further improve their applications and their development cycle.


AngularJS offers many of the same features as Angular. One of the fundamental differences is that AngularJS uses JavaScript instead of Typescript. The software is still used to develop single-page applications, just with a different set of code. AngularJS can allow people to more quickly develop their applications because it tries to enrich existing HTML, instead of creating a new code. It also has software in place that allows for projects to require less code, which makes them faster to develop and interface with.

Similarities between Angular and AngularJS

Listed below are some of the aspects that make both Angular and AngularJS similar to each other:

They both create single-page applications

You can use both software in the creation of single page applications. A single-page application is a website or web application that rewrites the current page, instead of loading up an entirely new webpage. Using a single-page application can offer many benefits to the user. These benefits can include faster loading times, easier application construction, and they use less bandwidth. While both software use different functions to create their applications, the end result is essentially the same. The needs of your single-page application can help determine which software you may want to use.

They both are extremely efficient

Both systems are very efficient at the tasks that they're required to do. AngularJS can create small single page applications with speed and allows for the user to make quick edits to their code. While Angular is more efficient at creating larger single-page applications. It's they designed systems to handle a larger flow of information so that it can still move with speed when it's processing more data. Having efficient software can make it easier to do your job and can help to improve your success and productivity.

They are both open-source software

Open-source software means that it's free for people to use and that it also may have a vast community who can support the software. This is beneficial because it means that it's less likely that the software may have errors. With a huge community of developers committed to maintaining the software, it may receive frequent updates that help to keep it current and working well.

For that same reason, open-source software is usually very reliable. When there is a bug detected, a countless number of people can fix it. This helps to make a reliable platform where people can safely work.

Differences between Angular and AngularJS

Below are several key differences between Angular and AngularJS:

Angular has mobile support

One big advantage that Angular has over AngularJS is that it supports mobile application development. A majority of people do a lot of work from their phones or tablets. They also spend much of their leisure time on these devices as well. Being able to use Angular to develop mobile-friendly pages makes it so that the content you're developing can be more accessible to a larger number of people. As the world becomes more mobile centric, this becomes a more crucial function.

AngularJS uses Model View Controller (MVC)

AngularJS uses MVC as the central component that all information is fed through. You place your input logic in the model and then your desired outcome as the controller. It then takes this information and creates the model and the view from that data. This system is very useful because it helps you to manage your data, and gives a better expression of how your application may work. This system also manages all the rules and logic of your application. Having this system can make creating an application more organized and efficient.

Angular is more efficient at making large applications

Angular really excels when it comes to creating larger applications. In general, Angular has a better structure for managing large amounts of code. Since larger single-page applications take more data to create and run, Angular is able to build and render the application easier and quicker. Much of this is due to the Ahead-of-Time compilation, which transfers TypeScript and HTML into JavaScript as they built the site, which leads to faster loading times, and more efficient compiling of code.

AngularJS reduces construction time of applications

Since AngularJS focuses more on enriching current HTML code, this can help to speed up the construction time of applications significantly. It also uses a two-way data binding to speed up construction. This means that the components and the templates share data. For example, if you change some of the information that is included in the template, it can automatically update in the components. This saves you time and effort in changing information in two places, and by extension speeds up the entire process.

Angular uses Typescript

Microsoft created Typescript, and mostly maintains the software as well. While JavaScript is the more common industry standard, Typescript has some features that JavaScript doesn't. Typescript allows for more precision, increased performance, and improved code management. Since some of the largest industry leaders also used TypeScript, it comes with more support for current and older versions. The software also automatically converts to JavaScript so that your work can seamlessly flow between both software. The precision of Typescript and its templates also can allow for more reactive programming.

AngularJS uses JavaScript

JavaScript is one of the more common coding software. This helps when it comes to finding resources on how to use it and support when it isn't working. JavaScript is relatively easier to learn for beginners, which is why so many people use it. The system is also robust enough that it can perform a wide range of tasks.

Once you become used to JavaScript's language, it can be very quick to use since it reads an interpreted language that the system can process faster. The number of resources available and the number of people working on JavaScript make it a very reliable open-source software.

Angular uses directive-based architecture

Angular uses a series of components and directives to control the Document Object Model (DOM). This uses pre-defined template directives to help guide the DOM. There are two types of directives that are typically in this style of architecture. The first may be structural directives. You can replace parts of a structural directive to change the layout of the DOM. The second directive is an attributive directive. If you make an adjustment to one of these directives, you can affect how different parts of the DOM may appear.

AngularJS uses third-party support

While Angular has an internal support system, AngularJS has to use third-party support to help its software. These support software can help to automate certain functions and make it easier to handle more complex functions. Without these support systems, it may be a lot more difficult to manage your data and build your applications. The reason that only AngularJS uses these supports is that they read JavaScript, not Typescript.
