⚡ JavaScript & TypeScript Daily Refresher #88 👉 What is a “never check” in TypeScript? 💡 A never check happens when TypeScript confirms that all possible cases of a union are handled — anything left falls into the never type, helping you catch missing branches at compile time. ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #AdvancedTypes #WebDevelopment

⚡️ 2025 JavaScript framework VS 2010 Backbone (aka The OG) ⚡️ « The interesting part is not how much better a modern framework is—it's how little progress we've actually made »

⚡ JavaScript & TypeScript Daily Refresher #80 👉 What makes abstract classes different from interfaces in TypeScript? 💡 Abstract classes can include method implementations, while interfaces only define method contracts — no actual code inside them. ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #OOP #WebDevelopment

⚡ JavaScript & TypeScript Daily Refresher #74 👉 What are the most important components of classes in JavaScript and TypeScript? 💡 Classes mainly include properties, constructors, and methods. In TypeScript, you can also define access modifiers like public, private, and protected for better structure and encapsulation. ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #OOP #WebDevelopment

🚀 New video from my “Everyday JavaScript Topics” series! Today I explained Default Parameters in JavaScript — from ES5 to ES6 — with real examples and visual breakdowns. Covered in the video: ✔ ES5 vs ES6 default handling ✔ Expressions as default values ✔ Using previous parameters ✔ undefined vs null ✔ Sequential rule ✔ Common mistakes If you're learning JavaScript or improving your fundamentals, this will really help! 👉 Watch here: https://lnkd.in/g2MZ99W8 #javascript #webdevelopment #programming #codingMeAaja

⚡ JavaScript & TypeScript Daily Refresher #89 👉 What are function overloads in TypeScript? 💡 Function overloads let you define multiple call signatures for one function, so TypeScript can offer better type safety and autocomplete based on how the function is called. ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #FunctionOverloads #WebDevelopment

⚡ JavaScript & TypeScript Daily Refresher #86 👉 I have a type that’s a union of multiple types — what’s the side effect of using it? 💡 Unions can cause more complex narrowing because TypeScript must consider all possible types, which can lead to extra checks before accessing properties or calling methods. ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #TypeNarrowing #WebDevelopment

⚡ JavaScript & TypeScript Daily Refresher #77 👉 What is the return type of a setter function in TypeScript? 💡 Setter functions should not have a return type at all — they’re meant only to update a property’s value, not return anything. ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #OOP #WebDevelopment

⚡ JavaScript & TypeScript Daily Refresher #63 👉 What are some bad practices in TypeScript? 💡 ❌ Adding type annotations everywhere — it reduces readability when inference already works. ❌ Overusing any — it defeats the purpose of TypeScript’s type safety. ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #CleanCode #BestPractices

Backend renamed profile to userProfile last Tuesday. TypeScript didn't warn you because of `any`. User clicked Settings. White screen. Slack exploded. This is the cost of `any`. Silent failures. Runtime surprises. Bugs TypeScript was designed to catch. Read my blog below in the comment 👇🏽 #TypeScript #JavaScript #WebDev #SoftwareEngineering #DeveloperLife
