A collection of reusable code organized into functions, objects, and variables, designed to be imported and used by other parts of the application.

Modules that are built-in to Node.js, providing core functionalities like handling HTTP requests, file system interactions, or operating system information.

Modules that developers create within their applications to organize their code into reusable components specific to that project.

Modules that are not part of the Node.js core but are developed and made available for use by external developers through the Node Package Manager (NPM).

A powerful package manager used for installing, updating, and managing dependencies for Node.js projects.

The http module provides functionality for creating and managing HTTP servers and clients. It handles incoming requests, sends responses, and interacts with HTTP headers and status codes.

A popular open-source NoSQL database that stores data in JSON-like documents, providing flexibility and scalability for handling large amounts of information.

A document-oriented model used in MongoDB, where data is stored in flexible and human-readable JSON-like structures.

The capability of a system, like MongoDB, to expand its capacity by adding more resources, such as servers, to handle increasing data volumes.

A term that refers to databases that don't follow the traditional relational database structures, offering flexibility and scalability advantages.

A powerful command-line tool to interact with MongoDB databases. It allows developers and administrators to perform operations like creating, reading, updating, and deleting data.

A graphical user interface (GUI) for MongoDB. It provides a visual environment for interacting with databases, including features like data visualization, collection management, and query building.

The process of organizing and structuring data within a MongoDB database, taking into account the application's needs. It involves deciding how to represent data and relationships, unlike traditional relational databases.

A data storage approach where related data is contained within a single document. It keeps all relevant information together, simplifying retrieval and reducing the need for joins.

A data storage method that uses references to connect documents, minimizing data duplication and improving consistency, especially in large applications.

A popular and open-source JavaScript framework for crafting dynamic web applications. It extends HTML with new attributes and functionalities, simplifying the creation of complex user interfaces.

An architectural pattern widely used by Angular. It separates the application into three components: models (data and logic), views (user interface), and controllers (connecting models and views).

Reusable blocks of code in Angular that represent specific sections of the user interface. They simplify development and encourage code reuse.

A feature in Angular that allows data to flow in one direction either from a component to a view or vice versa. This ensures that changes in one place are reflected in the other.

Node.js is an open-source, cross-platform runtime environment for JavaScript that allows JavaScript to be executed outside of a web browser, enabling the development of server-side web applications.

Node.js was developed by Ryan Dahl in 2009, and its latest version is 15.14, released in April 2021. It's used for building data-intensive, server-side applications that need to handle many requests efficiently.

Node.js utilizes an asynchronous, event-driven model, which means it can handle multiple requests at once without blocking or slowing down, making it ideal for situations that need fast responses.

Node.js is built on the Chrome V8 JavaScript engine, which converts JavaScript code into machine-readable code rapidly, making it incredibly fast and efficient.

Node.js uses a single-threaded, event-driven architecture. It can manage multiple concurrent operations without blocking thanks to the event loop, which handles all the behind-the-scenes tasks.

Node.js is exceptionally fast due to its reliance on the V8 JavaScript engine. Its ability to execute code quickly results in efficient performance and fast response times.

Node.js's event-driven architecture allows it to manage a large number of concurrent connections without performance degradation, scaling effortlessly to accommodate increased traffic.

Node.js is well-suited for real-time applications, such as chat applications, gaming, and streaming, due to its asynchronous nature, which ensures quick responses and interactive experiences.

The Node.js community is vast and active, providing a wealth of ready-made libraries, packages, and frameworks that can simplify development, saving time and effort.

The Node Package Manager (NPM) is a package manager that simplifies dependency management in Node.js projects, making it easy to install, update, and manage the required libraries and packages.

Two-way data binding in Angular allows changes in both the view and the component to be reflected in each other automatically. This is typically used for interacting with form controls.

The 'src' folder in an Angular project contains the core application code including components, services, and models.

The 'app' folder within the 'src' folder contains the main application component. This component typically defines the structure and logic of the Angular application.

The 'app.component.ts' file contains the TypeScript code for the main application component. This defines the logic and behavior of the component.

The 'app.component.html' file contains the HTML template for the main application component. This defines the visual structure of the component.

The 'app.component.css' file contains the CSS styles for the main application component, defining its visual presentation.

Angular templates are HTML files that define the structure and content of a component. They are enhanced by Angular directives which add functionality.

The *ngIf directive conditionally renders an HTML element based on a boolean expression. If the expression is true, the element is displayed. Otherwise, it is hidden.

The *ngFor directive iterates over an array of items, rendering a template for each item. It's useful for displaying lists or data.

Property binding uses square brackets ([]) to bind a component's property to an HTML element's attribute. This lets you dynamically change attributes based on component data.
