JavaScript Hoisting Explained

🧠 Day 15 of 21days challenge Memoization in JavaScript ⚡ Why compute the same result again? Memoization stores the result of a function and returns the cached result when called with same input. For easy understanding :- Memoization = caching results Same input → no recomputation Improves performance 👉 That’s how expensive calculations are optimized This changed how I write efficient code 🚀 #JavaScript #Memoization #InterviewPrep #Frontend

💻 JavaScript Array Methods – Hands-on Practice Completed Worked on some fundamental Array methods in JavaScript and practiced how they actually behave 👇 ✔️ Used push() and pop() to add/remove elements from the end ✔️ Used unshift() and shift() to work with elements at the beginning ✔️ Explored length to track array size ✔️ Understood the difference between slice() and splice() through practice 💡 Key takeaway: slice() does not modify the original array, while splice() directly changes it — this difference is really important while working with data. Practicing these basics is helping me build a strong foundation in JavaScript 🚀 #JavaScript #WebDevelopment #Frontend #CodingJourney #LearningByDoing

JavaScript Promise chaining vs async/await: Promise chains: → Harder to read → Error handling complex → Callback-ish Async/await: → Reads like sync code → try/catch works naturally → Easier debugging The choice is obvious. #JavaScript #AsyncJS #CleanCode

A quick look at some powerful TypeScript features: • Generics (with constraints) • Conditional & Mapped Types • typeof & keyof These concepts make it easier to write flexible, reusable, and maintainable TS code.

What To Know in JavaScript (2026 Edition). Part 3. RegExp Improvements. Working with user input in RegExp has always been risky — special characters could break your patterns. New improvements solve this with safe escaping. A small but critical improvement: - fewer bugs - safer handling of user input - easier dynamic regex creation #frontend #webdev #javascript #performance

Six characters that completely changed how we write JavaScript. 👇 If your code is still cluttered with the function keyword, it’s time for an upgrade. Arrow functions () => {} aren't just syntactic sugar; they are the backbone of clean, modern JS. Swipe through the carousel to see: - Why developers prefer them - How they fix the classic this headache - Where they shine the most How often are you using arrow functions in your current projects? #JavaScript #WebDev #CleanCode #Frontend #Coding

JavaScript basics that still matter: let vs var vs const var: • Function scoped • Can be redeclared let: • Block scoped • Can be updated const: • Block scoped • Cannot be reassigned Small concepts, big impact on clean code. Which one do you use the most? #JavaScript #CodingTips #Frontend

Day 1/30 Write a function createCounter. It should accept an initial integer init. It should return an object with three functions. The three functions are: increment() increases the current value by 1 and then returns it. decrement() reduces the current value by 1 and then returns it. reset() sets the current value to init and then returns it. #30DaysOfCode #JavaScript #LeetCode #WebDevelopment #ProgrammingChallenge #CodingLife
