Debugging APIs with Regex in Network Tab

⚠️ `unknown` vs `any` is not just syntax They look similar But they lead to very different code Both can represent values with an unknown shape `any` is useful when you intentionally want to opt out of TypeScript `unknown` is useful when the value is uncertain, but you still want safety That is why `unknown` is usually the better default for external data And why `any` should be used very intentionally Where do you usually draw the line between `any` and `unknown`? #Typescript #React #Frontend #WebDevelopment #Javascript #ProgrammingTips #FrontendDevelopment #Coding #CodingTips

JavaScript destructuring with defaults: const { name = 'Guest', age = 18 } = user; No undefined values. No extra checks. No conditional logic. Defensive coding made elegant. #JavaScript #ES6 #CleanCode

JavaScript quirk that still confuses developers: typeof null === "object" This isn’t a feature. It’s a legacy bug. Understanding the difference between: null (intentional absence) undefined (not assigned) …prevents subtle bugs in production. #javascript #webdevelopment #coding

⚠️ JavaScript Mistakes Every Developer Should Know Even experienced developers make these mistakes… avoid them 👇 ❌ Using == instead of === 👉 Can cause unexpected results due to type conversion ❌ Forgetting return in functions 👉 Function runs but returns undefined ❌ Not handling asynchronous code 👉 Code executes before data is ready ❌ Mutating objects/arrays directly 👉 Can lead to unexpected bugs ❌ Ignoring this behavior 👉 this depends on how a function is called ❌ Using var instead of let/const 👉 Leads to scope-related issues 🔥 Key Takeaway: Small mistakes in JavaScript can lead to big bugs.

Javascript concept: Data Types A small mistake cost me hours debugging. let a = 10; let b = a; b = 20; console.log(a); // 10 But then: let obj1 = { name: "JS" }; let obj2 = obj1; obj2.name = "React"; console.log(obj1.name); // React 💡 Lesson: Primitives → copy by value Objects → copy by reference #JavaScript #WebDevelopment #Frontend #Coding

Hoisting is a behavior in JavaScript where variable and function declarations are conceptually moved to the top of their containing scope (either the global script or a specific function) during the compilation phase, before the code is actually executed. It is important to understand that your code isn't physically moved anywhere. Instead, the JavaScript engine allocates memory for variable and function declarations before it executes the code line-by-line. #javascript #hoisting #frontend #scripting
