1. Never miss out to unsubscribe

In order to be a part of the best Angular team, you must never come out with silly mistakes. You can never give the excuse of missed or failed to unsubscribe. Cleaning up the subscriptions then and there is an important part of Angular. Whenever you have completed the use of event JavaScript, many libraries are built along with it for that particular purpose.

Leaving it unsubscribed will never clear all those libraries. Failing to unsubscribe at regular intervals can cause memory leaks and does not pave way for effective coding. This will grow out to become a serious problem. So never miss unsubscribing the completed activities.

2. Keep codes organized

This is a significant tip not only for the angular developers but also to the developers of any platform. Always organize the code. This will create a good impression on the developer and also improves the readability. In the future, suppose if any issue rises you will be able to spot it easily and work on it in no time. Having a controller for the view of working with MVC is the most usual one. This is because the controller is the principal layer and it makes compact compartments for every area in the application.

Avoiding this method and adding up new concepts to the single controller and lead to a mess in the future. Whenever a bug arises, you will find it very difficult to clear it. Sometimes you may be pushed into a situation to completely rewrite the code which is a bigger headache.

Hence this cannot be used in the construction of the HTML documents. So, if you want to alter only DOM, use jQuery.

4. Never make direct changes to DOM

Sometimes, when will make changes to DOM directly from the controller itself, which is a major mistake. This can cause problems while refreshing the page, validation errors and more similar ones.

You can use Render2 service to make that edit.

5. Avoid acknowledging the same component in multiple modules

A component is the basic building block of an app in Angular. It is important that each component is acknowledged to make it visible and clear for the user. If you are announcing a similar type of component establish a connection between the modules, if not then you have to create shared information Ngmodule.

6. Always give it a check

Some people will fail to take an overview test of the application after its completion. Apart from testing each module, examining the overall app before its launch is also highly necessary. Many people miss out this point and let all their work go in vain after launch.

7. Improper use of Event handlers

Angular is a master when it is designing functionality for the button depending upon user input. But the point is you have to place all the logic in order to function properly.

8. Never declare with anonymous functions

Always use proper naming for the functions. Declaring anonymous functions will reduce readability. Hence be appropriate and standard while naming functions.

9. Assemble Scope binding

Angular has its own scope binding rules. If you commit any mistakes it will prompt the breakdown and aid you in arranging it. To avoid complexities while coding, assemble the scope properly.

10. Utilize Batarang without fail

Batarang is a Google Chrome extension that it used by angular developers to debug apps. Never fail to use this extension; it will give you additional confidence while you launch the app.
