Understanding the difference between Promises and async/await is essential for writing clean and efficient JavaScript code. Many developers use them interchangeably, but knowing when and why to use each can significantly improve code readability and performance. In this article, I’ve covered: • Key differences between Promises and async/await • Practical examples • Real-world use cases • Common pitfalls developers should avoid If you're preparing for interviews or improving your JavaScript fundamentals, this guide will be useful. 🔗 Read here: https://lnkd.in/gPQ3-55Y #JavaScript #SoftwareDevelopment #FrontendDevelopment #Programming #WebDev #AsyncAwait #Promises

Most JavaScript bugs don’t come from syntax… They come from 𝐦𝐢𝐬𝐮𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐬𝐜𝐨𝐩𝐞. Why does `var` behave differently from `let`? Why do closures “remember” variables? Why do some variables leak into global scope? If these questions have ever confused you, this is worth reading. Read here: https://lnkd.in/gybfSz6F #JavaScript #Coding #SoftwareEngineering

Just wrote a blog on the "new" keyword in JS Under the hood, new follows a precise process: • Creates a new empty object • Links it to the constructor’s prototype • Binds this to that object • Executes the constructor function • Returns the final instance If you're learning JavaScript or revisiting fundamentals, this will sharpen your understanding 👇 https://lnkd.in/gEitS7KJ #JavaScript #WebDevelopment #Frontend #Programming #Coding #LearnInPublic #Developers #SoftwareEngineering

I’ve started learning scope in JavaScript, but before diving into it, I took an interesting detour into a very important question: Is JavaScript compiled or interpreted? Before getting into scope properly, I learned that JavaScript does not behave like a simple line-by-line interpreter. A good example is this: ```js console.log("Hello"); function foo() { console....log("world"); } console.log("hello world"); ``` If JavaScript was executed in a purely naive line-by-line way, we might expect "Hello" to be logged before the error appears. But that does not happen. The script fails before execution starts because the JavaScript engine first goes through an initial preparation phase. That phase includes things like: 1. parsing the code 2. checking whether the syntax is valid 3. building an internal representation 4. preparing the code for execution So a better mental model is: Source code -> Parse / syntax check -> Internal representation / compilation steps -> Execution This helped me understand that calling JS simply “interpreted” is not the full picture. Modern JavaScript engines like V8 are much more advanced. They can parse code, create internal representations, interpret some code, compile parts into bytecode or internal instructions, and even JIT-compile frequently used parts for better performance. So JavaScript is commonly called an interpreted language, but in modern engines, the reality is more nuanced. This also connects nicely with scope. Scope is about the visibility of variables and functions in code, but before JavaScript can execute code, the engine first needs to understand the structure of that code. That means scope is not just a runtime topic. It is closely connected to how the engine reads, parses, and prepares the program. My main takeaway: JavaScript is not random, and it is not just “reading one line at a time”. There is a preparation phase before execution, and understanding that makes topics like scope, hoisting, and errors much easier to reason about. #JavaScript #TypeScript #WebDevelopment #SoftwareEngineering #V8 #LearningInPublic

New post on arrow functions in JavaScript, covering the basics with simple examples. Arrow functions are essentially a shorter way to write function expressions using the => syntax, introduced in ES6.

While learning JavaScript, one of the biggest challenges developers face is handling asynchronous code effectively. Concepts like callbacks and promises can quickly become complex — especially for beginners. That’s where Async/Await comes in. It simplifies asynchronous programming by making code more readable and maintainable. I’ve written a detailed article covering: • Clear explanation of Async/Await • Practical examples • Real-world use cases • Common pitfalls to avoid If you're improving your JavaScript skills or preparing for interviews, this might be useful for you. 👉 https://lnkd.in/gf9NBEmB Would love to hear your thoughts — do you think Async/Await has completely replaced Promises, or do both still have their place? #JavaScript #AsyncAwait #WebDevelopment #SoftwareDevelopment #Programming #Frontend #Developer #Coding #TechLearning #CareerGrowth

🚀 JavaScript Practice: Improving Logic with Real Examples 💡 🚀Today I focused on strengthening my core JavaScript skills by working on two small but powerful problems.🚀 1. Character Frequency Counting 💬I explored how to count how many times each character appears in a string like "racecar". This helped me understand how objects can be used to store and update values dynamically. I also learned how to transform that data into a clean, readable format.💬 📌 Key learning: 🔹 Using objects to track frequency 🔹 Converting data into a structured format 🔹 Building clean output instead of messy strings 2. Array Pair Formatting Next, I worked on converting an array into a custom pair format like [1:2, 3:4, 5:6]. This improved my understanding of looping with steps and grouping elements logically. 📌 Key learning: Iterating through arrays in steps Grouping elements into pairs Understanding the difference between actual data structures and formatted output 🔥 Overall Takeaways ✔ Improved problem-solving approach ✔ Better understanding of objects and arrays ✔ Learned how to format output cleanly and efficiently #JavaScript #CodingPractice #FrontendDevelopment #ProblemSolving #LearningJourney
