Inheritance is a concept in object-oriented programming where a class can inherit attributes and methods from another class.
Allows for code reusability by creating a new class based on an existing class
Derived class inherits properties and behaviors of the base class
Supports the 'is-a' relationship, where a derived class is a specialized version of the base class

CSS3 flexbox is a layout module that provides a more efficient way to align and distribute space among items in a container.
Flexbox allows for flexible and responsive layouts without using floats or positioning.
It uses a parent container and child elements with flexible properties to create the layout.
Properties include justify-content, align-items, and flex-wrap.
Flexbox is supported by all modern browsers.
Example:
Position property in CSS3 is used to set the position of an element relative to its parent or the viewport.
The position property can take values like static, relative, absolute, fixed, and sticky.
Static is the default value and elements are positioned according to the normal flow of the document.
Relative positions the element relative to its normal position.
Absolute positions the element relative to its nearest positio...
Closure is a function that has access to its parent scope even after the parent function has returned.
Closure allows for private variables and functions in JavaScript.
It is created when a function returns another function.
The inner function has access to the outer function's variables and parameters.
Example: function outer() { let x = 10; return function inner() { console.log(x); } }
Example: const innerFunc = outer();
Prototype is a property of an object that allows adding new properties and methods to an object.
Prototype is a blueprint for creating objects
It allows inheritance by sharing properties and methods between objects
Modifying the prototype affects all objects created from it
Prototype chain allows accessing properties and methods of parent objects
Example: Array.prototype includes() method
Pipe is a feature in Angular that allows transforming data before displaying it in the view.
Pipes are used to format and manipulate data in Angular templates.
They can be used to filter, sort, and transform data.
Pipes can be chained together to perform multiple transformations.
Angular provides built-in pipes like DatePipe, CurrencyPipe, and LowerCasePipe.
Custom pipes can also be created to meet specific requirements.
A directive is a component that adds behavior to an existing element or component in Angular.
Directives are used to manipulate the DOM, add event listeners, and create reusable components.
There are three types of directives in Angular: component, attribute, and structural.
Examples of built-in directives in Angular include ngIf, ngFor, and ngStyle.
Custom directives can be created using the @Directive decorator.
A component in Angular is a reusable piece of UI that consists of HTML, CSS, and TypeScript code.
Components are the building blocks of Angular applications.
Each component has its own logic and view.
Components can be nested within other components.
Components can communicate with each other using @Input and @Output decorators.
Examples of components include a login form, a navigation menu, and a product list.
Observables are a way to handle asynchronous data streams in Angular using RxJS library.
Observables are similar to promises but can handle multiple values over time.
They can be used for handling events, HTTP requests, and other asynchronous operations.
Operators can be used to transform, filter, and combine observables.
Subscriptions are used to listen to observables and receive data.
Example: fetching data from an API us
Event loop is a continuous process that runs in the background and handles all the events in the application.
Event loop continuously checks for new events in the event queue.
It processes each event one by one in a synchronous manner.
If an event takes too long to process, it can block the event loop and cause the application to freeze.
Event loop can be controlled using setTimeout(), setInterval(), and setImmediate() met...
