It is a very common fact that any programming platform or framework will have some myths regarding them. If you are looking towards studying and getting a certification in AngularJS or a professional who is planning for a shift in their career platform, certain facts regarding the myths revolving around AngularJS should be cleared at first. So we are here to enlighten you regarding those misconceptions.

One of the most common misconceptions regarding AngularJS is that the market for AngularJS developers has come down. There were some reports that came out in and around 2016 saying that the newer versions of Angular are much better than AngularJS.
AngularJS is basically the first version of Angular which is known for its ability of two-way data binding and has directives which makes the code reusable. Its dependency injection mechanism contributed significantly to the front-end application testing. The newer versions of Angular were developed with a motto to improve the performance but while aiming at the better performance and trying to reduce the use of directives in the newer versions, the developers ended up making it all the more complicated.
For example, In AngularJS, ng-model is used for creating two-way data binding and ng-bind for one-way data binding. Whereas in Angular, a single directive ngModel is used and if the user needs to go for single data binding, he should write it in ‘[ ]’ and if he needs to go for two-way data binding, it should be written in ‘[( )]’ complicating it in whole. Many directive names were changed when the transition happened from AngularJS to Angular.
To sum up, if the newer versions of Angular were as good as the developers had promised, 1.3 million developers would not be still sticking onto using AngularJS.
The main points that people quote while praising other frameworks is their compactness (especially Backbone JS and JQuery). Let’s have a quick look at some stats.

Approximations for minified and Gzipped versions :
|Ember 2.2.0||111 K|
|Angular 2 + Rx||143 K|
|React 16.2.0 + React DOM||31.8 K|
|Backbone JS||36 K|
Now that you have got a clear picture of the sizes of these frameworks, let’s have a small discussion over this topic. Let us disclose a secret to those people who complain about the bigger size of AngularJS. AngularJS is a framework that will on its own. You don’t have to necessarily add any server-side language for it to work. It is completely up to you to add it or not.
Whereas other frameworks, for example, Backbone JS has much stronger dependency on JQuery comparatively. So keeping aside the minimized size of the Backbone JS, when in use the size will be more as it largely dependent on JQuery.
So when in comparison (while in use), AngularJS’ size is not as huge as it is being portrayed.
This is another common myth that exists regarding AngularJS. Since it offers a feature that reduces the burden of buggy coding, it is often misinterpreted that it can be useful only in creating smaller web applications.
Advanced techniques of AngularJS have been used in creating bigger websites like The Guardian, Paypal, etc.
These websites are a proof that AngularJS framework can be effectively used to create complex websites in the field of e-commerce, entertainment, business, etc.
These large websites are a proof that less coding doesn’t always mean that those frameworks are designed for creating small applications. It is not true that they will not scale or won’t reach up to the mark that the enterprises expect. Even less code frameworks are capable of creating large-scale websites.
This is the most baseless myth that revolves around AngularJS. It actually is that framework that is most compatible while working with nested loops.
$scope. firstName = “John”;
$scope.name.first = “John”;
And it just works.
When multiple tabs are open on your laptop or desktop, as a reflex your system slows down. A similar scenario happens with AngularJS. Let me give you an example.
So let’s have a look at this code which is a nested ng-repeat with two bindings. Now, let’s imagine that there are 100 users and 10 skills. The command getTitle takes 1 millisecond to run. To do the initial render, this code takes 3 seconds. So an outsider so watches this will criticize that AngularJS is slow.
But this scenario occurs because AngularJS will often have to run the digest cycle multiple times in order to account for two way data binding. Here the problem lies in the command getTitle, so you can either optimise that function or pre-compute all the titles and just bind to primitives.
So basically the problem does not lie with AngularJS but with the inefficient expressions that are being used in the code.
You must have at least heard of Jeff Goodman who created one of the world’s most popular site for sharing codes, Plunker. But did you know this guy without any former technical training made this website with the help of AngularJS? Yes, you read it right. He had run into many problems while building the website but whenever such a problem arose Angular community came forward to support.
There are a wide range of content that has been produced to help you pass the learning curves like github repositories, egghead.io, etc.
This is another myth that revolves around AngularJS. The first concern that any enterprise would have will be regarding the security. This is because they have to ensure that the new frameworks that they are using does not create any holes in their security mechanisms. The security concern is not very severe with AngularJS as you don’t have to include any extra security practises than what you have been following so far in your organisation like the basic guard against injection attacks, secure sessions on the server, etc.
