What is Angular Js. ?
AngularJS is a very dynamic and quickly evolving framework. AngularJS is an open-source web application framework that offers quite a bit to a developer through a stable code base, vibrant community, and rich ecosystem. Let’s identify some of the high-level advantages of using AngularJS before we get into some of the more technical details of the framework.
Advantages of using AngularJS :
AN INTUITIVE FRAMEWORK MAKES IT EASY TO ORGANIZE YOUR CODE :
As previously stated, there’s a pressing need to be able to organize your code in a way that promotes maintenance, collaboration, readability, and extension. AngularJS is constructed in such a way that code has an intuitive place to live, with clear paths to refactor code when it has reached a tipping point. Do you have code that needs to provide information on how a user interface is supposed to look and behave? There’s a place for that. Do you have code that needs to contain a portion of your domain model and be available for the rest of the application to use? There’s a place for that. Do you need to programmatically perform DOM manipulation? There’s even a sane place for that as well!
TESTABLE CODE MAKES IT EASIER TO SLEEP AT NIGHT :
Testable code isn’t going to win any awards for being the most exciting feature of a framework, but it’s the unsung hero of any mature framework. AngularJS was written from the ground up to be testable, and likely this feature, along with the design decisions that came from this commitment, has played a huge role in the adoption of AngularJS. How do you actually know if your application works? The fact that it hasn’t broken yet is a flimsy answer, as it’s only a matter of time before that black swan shows up at your door. You can never entirely mitigate against bugs, but you can truly eliminate certain possibilities through rigorous testing. A framework that is conducive to writing testable code is a framework that you’re going to write tests in. And when you write tests, you’ll spend less time looking over your shoulder wondering when everything is going to come crashing down. You’ll be able to go to bed at night and not have to worry about a 2 a.m. call from DevOps that something has gone awry and you need to fix it immediately.
TWO-WAY DATA BINDING SAVES YOU HUNDREDS OF LINES OF CODE :
TEMPLATES THAT ARE HTML MEANS YOU ALREADY KNOW HOW TO WRITE THEM HTML is an inherently limited language that was designed to facilitate layout and structure, not complex interactions. In other words, it wasn’t created to live in the world of the modern web application as we know it now. Some frameworks try to overcome this limitation by abstracting out HTML entirely into strings or some preprocessor dialect. The problem is that HTML is actually good as a declarative mechanism and there’s this annoying reality about HTML—pretty much everyone knows it. If you’re working on a large team, there’s a good chance that you’re going to have a UI/UX contributor who’ll be responsible for generating your HTML templates. It’s important to leverage a workflow and skill set that they’re already familiar with, and AngularJS makes this a breeze. AngularJS embraces HTML while giving developers the ability to overcome its limitations by extending it to do whatever it is we need.
