AngularJS has been all the rage in the front-end development world, and with good reason—it’s an incredibly powerful JavaScript framework that makes building responsive websites quicker and easier than ever before. But despite AngularJS’s many benefits, it’s not right for every situation; there are some drawbacks to this powerful JavaScript framework that you should be aware of before you decide to use it on your project. Read on to learn more about the pros and cons of AngularJS so you can make an informed decision as to whether or not it’s right for your next project.

Why use it?

​AngularJS is a JavaScript-based open-source front-end web application framework mainly maintained by Google and by a community of individuals and corporations to address many of the challenges encountered in developing single-page applications. The JavaScript components complement Apache Cordova, a platform used to build native mobile applications using HTML, CSS, and JavaScript. It was created by Google employee Misko Hevery in 2009 to solve problems he encountered developing Enterprise Web Applications. The goal was to develop an open source library that provided MVC capabilities but with none of its complexity. Hevery became a member of Google's Site Reliability Engineering team where his job is to fight spam.

the major benefits of using Angulatr.js for web development includes

1.  MVC framework – The MVC (Model-View-Controller) architecture is a software design pattern that separates an application into three interconnected parts: model, view, and controller. The model contains all business data objects, their attributes, and methods to manipulate them. The view displays information based on these models in a user-friendly manner; it can be as simple as plain text or as complex as an HTML page with graphics and animations. Finally, controllers process user input from views and use models to update their data for display by views.

2.  Templating – Templates are HTML files that contain reusable chunks of code called directives. Directives are markers on a DOM element (such as an attribute, element name, comment or CSS class) that tell AngularJS's HTML compiler to attach a specified behavior to that DOM element or even transform the DOM element and its children. This process is known as transclusion. The compiled version of a template is called a template instance. Templates allow you to separate presentation code from application logic. It also helps to maintain better separation between designers and developers because designers can work on templates independently without knowledge of programming languages used in application development.

3.  Two-way data binding – This feature automatically synchronizes models with views whenever either one changes, eliminating unnecessary code required to maintain synchronization between model and view objects. The framework detects any changes in bound properties, immediately propagates these changes to all dependent views, while also providing hooks for firing custom events into both frameworks when a property is changed. This behavior is similar to front-end frameworks such as Knockout or Angular 2, which are based on two-way data binding as well. 

4. Dependency injection – Dependency injection is a software design pattern that implements inversion of control for resolving dependencies.

Why not to use it?

One of my main concerns is hiring angularjs developers to create an application with it. Developers seem to either love or hate AngularJS. Since it’s just a framework, you’ll want to make sure your hired developers are aware of how much time will be needed to learn it before making a commitment. This can save you lots in initial fees and headaches later on down the road. Developers also tend to run from frameworks that require you to use shims or other workarounds for certain functionality; these are typically related to cross-browser issues (and no matter what anyone says, most mobile development projects still start on desktops). I prefer using frameworks that let me do things the right way, meaning modern browsers only!

Why should you avoid using it?

The biggest pro that developers can hire angularjs development company is that it’s flexible. However, with a title like Flexible JavaScript MVW Framework, its flexibility is actually one of its cons. It’s considered opinionated, which means you have to bend to fit it into your existing way of doing things; but without having used it before, you don’t know if it fits with how you do things. Also, it requires more time from both employers and employees than other JavaScript frameworks because there is so much to learn with each change in direction.

Why should you consider using it?

Not every new technology is right for your business. There are plenty of people out there who see something new that sounds cool or disruptive and immediately jump on board. That's fine, but it isn't always a wise decision—especially if you’re looking to change something as fundamental as how your company works. But deciding whether or not to build an app in AngularJS should take some time. And if you hire a developer, you'll have more time to think about your business goals and talk about your strategy with your team before writing code. There are definite reasons why businesses would be drawn to using AngularJS: Speed can be among them; with it, you don't need to use as many lines of code.
