Think you can start a new line after `return`? Cute. JavaScript's "helpful" semicolon insertion will stab you in the back. `return\n{ user: 'Gabo' }` becomes `return;`. Your function now silently returns `undefined`. The object vanishes. Is this a clever rule for cleaner code, or a silent logic-killer that semicolons exist to prevent? #GaboTips #JavaScript

JavaScript for 15 Days – Day 6: If / Else Statements. Today you'll know how to make your JavaScript code think and decide using if, else if, and else statements. These structures allow programs to run different blocks of code based on specific conditions just like real-life decisions: let score = 85; if (score >= 90) { console.log("Excellent!"); } else if (score >= 70) { console.log("Good job!"); } else { console.log("Keep practicing!"); } Key Takeaways: if checks the first condition. else if tests another one if the first fails. else runs only when all above are false. Conditional statements are what make code dynamic and smart they let programs respond to different situations! #JavaScript #FrontendDevelopment #WebDevelopment #CodingJourney #LearnToCode #15DaysJS #DevPerDay

🚀 JavaScript Trick You Should Know! What do you think the result will be? 👇 "5" + 2 // ? "5" - 2 // ? ✅ "5" + 2 → "52" ✅ "5" - 2 → 3 Why? Because (+) combines strings, while (-) forces JavaScript to convert "5" into a number. A small example — but it shows how type coercion can completely change your output. ⚡ #JavaScript #FrontendDevelopment #CodingTips

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

🤔 What's the difference between 𝗺𝗮𝗽()and 𝗳𝗹𝗮𝘁𝗠𝗮𝗽() in #JavaScript? #map() transforms each element in an array and returns a new array with the same length. #flatMap() does the same but flattens nested arrays by one level, perfect for unwrapping results without extra .flat() calls! This makes your code shorter and more efficient for handling nested data. Which do you prefer using in your projects, and why?

Going back to basics 🌱 What does "typeof null" returns ?? Surprisingly, it returns "object" Yes it has been a "bug" in Javascript since the very beginning as i have read. When Javascript was first designed, values were stored in a way that caused "null" to be mistakenly tagged as an "object". And even after years, it remains that way for backward compatibility. So, "typeof null" is "object" but null is not an "object". #Javascript #Frontend

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
