Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions. Why use it? Functional programming promotes immutability, higher-order functions, and declarative code, leading to cleaner, more predictable code. Best practices include avoiding side effects and using pure functions. Functional programming gained prominence in the 1950s.

Version control is a system that tracks changes to files over time, allowing multiple contributors to manage and merge changes. Why use it? Version control helps developers collaborate, avoid conflicts, and maintain a history of code changes. Best practices include committing frequently, using descriptive commit messages, and branching for features. Version control has been widely used since the 1980s.

CRUD stands for Create, Read, Update, and Delete—the basic operations for managing data in applications. Why use it? CRUD operations are foundational to database management, allowing developers to create and manage records in a structured way. Best practices include using proper validation and error handling to ensure data integrity. CRUD has been a core concept since the early days of computing.

Husky is a tool for managing Git hooks, allowing you to run scripts before or after certain Git commands. Why use it? Husky helps enforce code quality by running linters or tests before committing code. Best practices include using Husky for pre-commit hooks to automatically format and lint code. Husky was first released in 2017.

Azure Active Directory (AAD) Auth is a cloud-based identity and access management service from Microsoft. Why use it? AAD Auth simplifies authentication and authorization, enabling secure access to applications. Best practices include using multi-factor authentication (MFA) and conditional access policies. Azure AD has been available since 2010.

Environment variables (often stored in .env files) are key-value pairs used to configure application settings. Why use it? They enable you to store sensitive data like API keys and configurations outside the codebase. Best practices include storing environment-specific configurations and using libraries like dotenv. Environment variables have been used for decades in software development.

Yarn is a package manager for JavaScript, designed to be faster, more secure, and more reliable than npm. Why use it? Yarn improves performance by caching dependencies and supports deterministic builds. Best practices include using Yarn for managing dependencies in large-scale projects. Yarn was first released in 2016.

Azure DevOps Pipelines is a cloud service that automates the building, testing, and deployment of applications. Why use it? It integrates with Azure services and supports multi-platform environments, improving continuous integration and deployment. Best practices include automating testing and deployment pipelines for faster delivery. Azure Pipelines was introduced in 2018.

D2Lang is a domain-specific language used for defining structured documents and diagrams. Why use it? D2Lang makes it easier to represent information visually, ideal for creating complex flowcharts or system designs. Best practices include using it for documentation and project visualization. D2Lang has been used since the early 2010s.

Architecture in software refers to the high-level structure of a software system. Why use it? Good software architecture ensures scalability, maintainability, and performance. Best practices include using design patterns, separating concerns, and ensuring modularity. Software architecture has been a focus since the 1960s.
