Learn how to create functions on-the-fly with one-liners using arrow functions and IIFE. This post covers practical patterns-factories, currying, closures, and event-handling examples-plus pitfalls and best practices.
A practical, hands‑on look at performance differences between the Function constructor (new Function) and traditional JavaScript function declarations/expressions. Includes benchmark code, explained results, and clear guidance on when to use each approach.
Self-executing patterns like IIFEs and async IIFEs are more than clever tricks. Learn how to use them for encapsulation, safe initialization, singletons, and complex game mechanics - and when ES modules are the better choice.
A practical guide to the core JavaScript concepts you need to explain and demonstrate in whiteboard interviews: closures, scope & hoisting, 'this', prototypes, asynchronous programming, and the event loop-plus how to present solutions clearly on the board.
Master how closures and lexical scope influence immutability in JavaScript interview problems. Learn patterns, pitfalls, and practical techniques-plus sample interview questions and clear solutions-to write predictable, testable code.
