The essential elements of Angular are as follows:

• Component: These are the fundamental units that make up an angular application and are used to manage HTML views.
• Modules: An angular module is a group of the framework's fundamental building parts, such as components, directives, and services. Each logically separate piece of code that performs a specific task is referred to as a "module" and is part of an application.
• Templates: These stand in for an Angular application's views.
• Services: They are used to build parts that may be used by the entire application.
• Metadata: This can be used to enrich an Angular class with additional data.
• Databinding: The DOM and application data are connected via binding markup. Event binding and property binding are the two different types of data binding.
• Directives: The logical structure is provided by template directives. Before a view is presented, Angular resolves the binding syntax in the template and evaluates the directives to make changes to the DOM and HTML components. This is carried out in accordance with the logic and data of the program .
