6. Using “trackBy”Along With ‘ngFor’

‘ngFor’ allows Angular developers to quickly re-render the whole DOM tree after making any significant changes in the array. It will eventually help Angular make DOM changes specific to the defined array rather than re-rendering DOM.

Angular re-renders is one such process that will take more loading process and typically take more time than utilizing ‘trackBy’.

If you are using ‘ngFor’ like:

7. Using Interfaces

Interfaces are crucial, especially when a contract for a class needs to be created. Additionally, it aids in the creation of the class needed to implement the functions and attributes specified in the interface.

As an illustration, consider how the class HomeComponent implements the OnInit and OnDestroy methods in the Angular application.

You may manage object literals with the help of interfaces. Our object must implement every property of the interface if it is an interface type.

8. Single Responsibility Principle

Avoiding the creation of several components, services, or directives inside of a single file is one of the fundamental Angular best practices that every developer must adhere to.

The single responsibility concept states that each file in an Angular application should only be in charge of creating a single, distinct functionality. We keep our files organised, readable, and maintained with the support of the single responsibility concept.

9. Make a Habit of Using Safe Navigation Operator (?)

To be on the safe side, programmers can only access a property directly from one object in a component's template by using the safe navigation operator.

When attempting to access a property for a null object, an exception will be raised. The template will disregard the null value and access the property once the object is no longer null, however, if they develop a habit of using the save navigation (?) operator, they will be able to access it.
