ES6 (ECMAScript 2015) is the sixth edition of the ECMAScript standard, introducing new features like classes, modules, and arrow functions to JavaScript. Why use it? ES6 makes JavaScript code cleaner, more modular, and easier to manage. Best practices include using let/const over var and taking advantage of modern JavaScript features. ES6 was finalized in 2015.

JavaScript is a high-level, dynamic programming language used to create interactive web applications. Why use it? JavaScript is essential for adding interactivity, controlling multimedia, and handling events on web pages. Best practices include using ES6+ features like arrow functions, promises, and async/await. JavaScript was first developed in 1995.

Node.js is a JavaScript runtime built on Chrome's V8 engine for building server-side applications. Why use it? Node.js offers fast performance and scalability, making it ideal for real-time applications and APIs. Best practices include using async/await, modularizing code, and using event-driven programming. Node.js was first released in 2009.

Object-Oriented Programming (OOP) is a programming paradigm based on objects that contain data and methods. Why use it? OOP promotes code reusability, scalability, and maintainability by organizing code into modular, reusable components. Best practices include following principles like encapsulation, inheritance, and polymorphism. OOP gained popularity in the 1980s.

Lodash is a JavaScript utility library that provides modular, performance-optimized functions for common programming tasks. Why use it? Lodash simplifies complex operations like deep cloning, data manipulation, and iteration, improving code readability and maintainability. Best practices include using the appropriate Lodash methods to reduce boilerplate code. Lodash was first released in 2012.

A promise in JavaScript is an object representing the eventual completion or failure of an asynchronous operation. Why use it? Promises provide a cleaner, more manageable approach to asynchronous programming compared to callbacks. Best practices include chaining promises and handling errors with `catch`. Promises became a standard in JavaScript in 2015.

Catching exceptions is a programming practice that involves handling errors in a controlled way during runtime. Why use it? Exception handling allows applications to gracefully recover from errors, preventing crashes and improving user experience. Best practices include using specific exception types and logging errors for debugging. Exception handling has been a core concept since the 1980s.

Pipe chaining is the technique of passing the result of one operation directly into the next operation in a sequence. Why use it? Pipe chaining improves readability and maintains functional purity in code. Best practices include chaining functions that operate on the same data type and avoiding side effects. This technique is commonly used in functional programming.
