🚀 JavaScript Interview Essentials: Callbacks vs Promises Ever wondered why callbacks feel like a tangled mess, but promises save the day? Callbacks: Just a function you pass around and call later—like handing off a task to a friend. 🏃♂️ Promises: A smart object that says "I'll let you know when I'm done" (pending, fulfilled, or rejected). It chains beautifully! ⛓️ Ditch callback hell (those deep nests!) for promises' clean .then() and .catch() flow. Which do you prefer in your code?
