JavaScript Callbacks Explained

The slice() method helps you extract specific parts of a string without modifying the original value. Simple, powerful, and super useful in real-world projects. Keep learning, keep building 💻✨ #JavaScript #WebDevelopment #FrontendDevelopment #Coding

JavaScript – Day 19 🚀 Error Handling in Async Code (try / catch) Handling errors properly is critical when working with asynchronous JavaScript. In this post, I’ve explained: 1. Error handling with promises 2. Error handling using async / await 3. Why try / catch is the recommended approach 📌 Day 19 of my JavaScript learning series.

JavaScript – Day 18 🚀 Promise.all vs Promise.race When working with multiple asynchronous tasks, JavaScript provides Promise.all() and Promise.race() to manage them efficiently. In this post: 1. Promise.all() waits for all promises to complete 2. Promise.race() returns the result of the fastest promise These methods are commonly used in real-world applications like API calls and parallel tasks. 📌 Day 18 of my JavaScript learning series.

JavaScript – Day 17 🚀 Async / Await (Simplified) 1. Async/await provides a cleaner and more readable way to handle asynchronous operations in JavaScript. 2. Instead of chaining .then(), async/await lets us write async code that looks synchronous. 📌 Day 17 of my JavaScript learning series.

JavaScript – Day 15 🚀 Event Loop (Call Stack & Callback Queue) JavaScript is single-threaded, but it can still handle asynchronous operations using the Event Loop. In this post, I’ve explained: Call Stack Web APIs Callback Queue How async code actually runs Understanding the Event Loop is crucial for writing efficient and bug-free JavaScript. 📌 Day 15 of my JavaScript learning series.

Building Blocks: JavaScript Variables Solidified a core concept today: JavaScript variables. Understanding let, const, and the legacy var is more than just syntax—it's about intent, scope, and writing predictable code. const:  for values that shouldn't be reassigned. let:  for variables that will change. Understanding scope prevents unexpected bugs. It's a fundamental step, but strong foundations enable everything built on top. Onward to the next concept! #JavaScript #WebDevelopment #Coding #ProgrammingBasics #LearningToCode #SoftwareDevelopment #Tech #Variables

JavaScript Array Functions – map() vs filter() 🔍 One of the most common confusions for JavaScript learners is understanding the difference between map() and filter(). In this post, I’ve explained: 1. map() → transforms each element in an array 2. filter() → selects elements based on a condition Both return new arrays, but they are used for different purposes in real-world applications. 📌 This is Day 3 of my JavaScript Array Functions series.

JavaScript – Day 16 🚀 Promises (then / catch / finally) Promises are used to handle asynchronous operations in JavaScript in a clean and readable way. In this post: 1. How promises work 2. Success (then) vs error (catch) 3. Cleanup using (finally) Understanding promises is essential before learning async / await. 📌 Day 16 of my JavaScript learning series.

JavaScript Array Functions – reduce() reduce() is one of the most powerful (and confusing) array methods in JavaScript. It takes all the elements in an array and reduces them into a single value using an accumulator. In this post, I’ve shown: 1. How the accumulator works step by step 2. Why the initial value is important 3. How reduce() combines values across the array Common use cases: 1. Calculating totals 2. Aggregating data 3. Counting or grouping values 📌 Day 4 of my JavaScript Array Functions series.
