Why is my asynchronous code not working as expected? Asynchronous JavaScript can feel confusing at first—things run “later,” errors seem to disappear, and loops don’t behave how you expect. This guide shows the most common mistakes and simple fixes with easy examples.

Ever wondered how to swap two variables in JavaScript without needing a temporary variable? Array destructuring can help! This modern JavaScript feature allows assigning variables from arrays or objects. Instead of the old-school three-line swap with a temp variable, you can achieve the same result in a single, elegant line. Check the example in today's trick snippet!

A Practical Guide to JavaScript Promises: Real-World Usage Promises are a fundamental part of modern JavaScript, yet many developers only scratch the surface of what they can do. We all learn the basics with a simple fetch call, but when should we really reach for them? And more importantly, when should we not?

Day 43/100 - #100DaysofCode Today I learned about the bind() method in JavaScript. It is used to permanently attach a specific this value to a function. When we call that new function, it always uses the bound this. Example: If we want to use a method of an object somewhere else but still keep the same this, we use bind().

🚀 Did you know? In JavaScript, await doesn’t block the whole code — it only pauses inside the async function! 🧠 Why? Because await splits the async function into two parts . The first runs synchronously, and the rest runs later as a microtask (after current code finishes but before setTimeout, etc.). “await says — I’ll continue later, but only after the main code finishes.” I think javascript is so confusing. What do you think? 💡 Takeaway: Understanding how await really works helps you avoid surprises in async code execution. #JavaScript #AsyncProgramming #WebDevelopment #CodingTips #EventLoop #letsLearnWithPrateek #Day8

🚀 Understanding compose() vs pipe() in JavaScript Have you ever wondered what the difference is between compose and pipe functions in JavaScript? They both let you combine multiple functions — but the order of execution makes all the difference! ⚡ 🧠 Key takeaway: compose runs functions right-to-left pipe runs functions left-to-right Both are powerful tools for creating clean, reusable, functional code. 💡 Pro tip: Use compose when you think in mathematical order, and pipe when you think in execution order (step by step). #JavaScript #FunctionalProgramming #CodingTips #WebDevelopment #ComposeVsPipe

🚀 Exploring JSON methods in JavaScript! I’ve shared a simple demo that shows how to: Convert a JSON string into a JavaScript object using JSON.parse() Convert a JavaScript object back into a JSON string using JSON.stringify() Check out the full implementation on GitHub: 🔗 https://lnkd.in/dK2fajsP #JavaScript #FullStack #100xDevs #WebDevelopment #Coding #100DaysOfCode

Ever struggled with TypeScript's type assertions losing literal types? 🤔 The `satisfies` operator is your 2025 solution for maintaining both type safety and specific literal values! When you use `as` assertions, TypeScript widens your literal types to their base types. The `satisfies` operator ensures your object matches a type while preserving the exact literal values you provide - giving you the best of both worlds. → Preserves literal types ("hello" vs string) → Maintains type safety → No more unexpected type widening → Perfect for configuration objects Have you adopted `satisfies` in your TypeScript workflow yet?
