Converting input type number in JavaScript with valueAsNumber

#javascript #javascriptTips Converting input type number by using parseInt or Number() function or using a plus operator for instance const num = +value. We can instead use the valueAsNumber property which gives the value as number type simple 🪄 Picture Credit: Steve Sewell 🙌

The “Result Pattern” is a great way to improve not only the code flow, but also the developer experience for those who’ll work with your code down the line. No need to try/catch random errors and guess error codes, everything is typed and you know exactly what you want/need to handle. #javascript #typescript #developerexperience #designpatterns #softwaredevelopment

In the upcoming Webiny v6, we’re rewriting a lot of internals, and the public API for extensions will be completey new. As we’re rewriting things, we’re taking the opportunity to improve the code base and DX for external teams but also for ourselves. This is just one example: the “Result Pattern”. Widely used in C#, proved to be a great pattern for managing and documenting a variety of potential errors that can be returned as a result of an operation. And not a single try/catch is necessary!! 🥳 #designpatterns #developerexperience #softwaredevelopment

The JavaScript filter() method is a powerful way to create a new array containing only the elements that meet a certain condition. It goes through each item in the array and returns the ones that pass the test you provide. For example, to get all even numbers from an array: javascript const numbers = [1, 2, 3, 4, 5]; const evens = numbers.filter(num => num % 2 === 0); console.log(evens); // Output: [2, 4] Use filter() whenever you need to sift through data and extract only what’s relevant, making your code more declarative and concise! #JavaScript #WebDevelopment #CodingTips #ArrayMethods

Difference between querySelector and querySelectorAll ✨ querySelector → grabs the first matching element only, returns 1 element or null. Use it when you need one specific element. 🌟 querySelectorAll → grabs all matching elements, returns a NodeList. Perfect when you want to work with multiple elements at once. #JavaScript Shubham Kumar Singh

𝐈 𝐛𝐞𝐭 𝐲𝐨𝐮 𝐝𝐢𝐝𝐧’𝐭 𝐤𝐧𝐨𝐰 𝐭𝐡𝐢𝐬… . . . There’s a 30-𝐲𝐞𝐚𝐫-𝐨𝐥𝐝 𝐛𝐮𝐠 in JavaScript — and it’ll never be fixed. 𝐭𝐲𝐩𝐞𝐨𝐟 𝐧𝐮𝐥𝐥 === "𝐨𝐛𝐣𝐞𝐜𝐭"; // 𝐭𝐫𝐮𝐞 🤯 This is not a quirk — it’s a mistake. When JS was created in 1995, 𝐧𝐮𝐥𝐥 was stored as all 0’s in memory. Objects also used 0 as a type tag. So JS confused them. Now fixing it would break the web. 💀 #JavaScript #ProgrammingHistory #WebDev #JavaScript #WebDevelopment #ProgrammingHistory

🚀 Day 19 of 30 Days of JavaScript – LeetCode Problem: 1207. Unique Number of Occurrences Today’s challenge was all about checking whether the number of occurrences of each value in an array is unique. ✅ My Approach 1️⃣ Count occurrences I used a for...of loop to count how many times each element appears in the array. 2️⃣ Store frequency results This gives me an object holding the occurrence count of every unique item. 3️⃣ Convert to a Set I extracted the values and converted them into a Set using new Set(), since a set automatically removes duplicates. 4️⃣ Compare values Arrays and sets can’t be directly compared, so I converted both to strings using JSON.stringify() to compare their datatype + values. 5️⃣ Return result If both match, I return true; otherwise, false. #JavaScript #LeetCode #30DaysOfCode #codingjourney #developerlife

Think the `+` sign is only for adding numbers? Adorable. It's also a lightning-fast type cast. `const pages = +"50";` turns a string into a number. But feed it `"50 pages"` and it silently returns `NaN`, poisoning every calculation that follows. Is this a brilliant, high-performance tool, or a cryptic bug-factory that `parseInt()` was designed to prevent? #GaboTips #JavaScript

🔍 JavaScript Insight: Object Equality by Reference Ever wondered why two objects with identical properties still return false when compared with ===? This quick snippet is a reminder that in JavaScript, objects are compared by reference—not by value. ✅ obj1 === obj3 → true (same memory reference) ❌ obj1 === obj2 → false (different objects, even if identical) Understanding this is key when debugging, designing data flows, or working with state management in React or backend logic. #JavaScript #WebDevelopment #FullStack #CodeTips #DeveloperNotes #ReactJS #InterviewPrep
