What are The Benefits of Using Angular JS?
AngularJS is a JavaScript framework that is maintained by Google and the open source community. Because of its ties to Google, and the popularity of the Google Chrome browser and Google’s Android platform, it makes sense to assume that it will be commonly supported and continue to be maintained and a strong choice for development for years to come.
1. Flexibility
AngularJS allows the web-page developer to add functionality to web pages by adding additional commands intermixed with the standard HTML. Unlike some JavaScript implementations, it is possible to freely intermix AngularJS with HTML and apply HTML styling to variables or only display HTML elements dependent on a function or variable. This flexibility and extensibility of HTML make it very attractive for creating small but powerful websites that have minimal server overhead.
2. Less loading
Because AngularJS is derived from JavaScript, it is a client-side language. This means that nearly all the work is done on the end-user’s computer, other than making servers occasionally return data. An MVC model is deployed, which stands for Model – View – Controller, and means that the client computer takes user input and performs most of the manipulations, as well as displaying the results. It only communicates with the server as necessary, calling or passing information but doing so within the loaded page on the client machine, rather than requesting a new page each time. This is actually very fast for the client, as there are much fewer network requests, and very light on the server in terms of both bandwidth and processing.
3. Easy deployment and maintenance
AngularJS is primarily used to create Single Page Applications (SPAs), which means that only the necessary information is loaded and displayed once the page (application) has loaded. This gives much finer control on what information is requested and returned, and makes the site ideal for mobile devices or even converting into a mobile app. This allows for one code base that can perform across all devices and uses, which makes for more rapid deployment and easier maintenance.
4. TypeScript support
There is also TypeScript support, which is a super-set of JavaScript and, again, allows for more efficient and simpler code to be written. It allows the use of ES6 notation which, while not fully supported by many browsers, allows for smaller file size and smaller, faster functions.
Summary
In summary, the benefits of AngularJS are: readable and easily maintained code, small file sizes, reduced server load, speed, wide-spread support, functionality, portability and a degree of future-proofing.
