Wrapped up with IIFEs & Closures today. IIFEs = functions that run immediately after being defined (great for one-off setups). Closures = functions that “remember” variables from their outer scope even after that scope is gone. Powerful stuff for encapsulation & state #JavaScript

Functions returning functions 🤯 It felt weird at first, but now it’s like building your own tiny factories of behaviour. Super cool concept. #CodeNewbie #JavaScript

Practised writing functions that accept callbacks. Such a simple idea, but it makes code modular and powerful. #JavaScript #webdev

Learnt the difference between first-class and higher-order functions. In JS, functions are first-class citizens – you can store them, pass them, return them… and higher-order functions take it to the next level 🔥 #JavaScript #CodeNewbie

Passing arguments by value vs. reference finally clicked for me today. Helps to know what actually gets changed when you call a function 👌 #webdev #JavaScript

Default parameters in JS are a game-changer. You can set fallback values right inside the function definition. Makes functions cleaner & less error-prone 💡 #JavaScript #CodeNewbie

Started the “A Closer Look at Functions” section on Friday and wrapped it up today 🎯 It’s been one of the most eye-opening parts of the course so far! #JavaScript #webdev #CodeNewbie

Wrapped up the Data Structures, Modern Operators & Strings section today 🎉 Big thanks to @jonasschmedtman for making this course so practical 🙌 #JavaScript #webdev #CodeNewbie

Also played with methods like toLowerCase(), toUpperCase(), replace(), includes() & startsWith() 🙌 So many little helpers that make text handling smooth. #JavaScript #CodeNewbie #webdev

Dove deep into JavaScript strings — from split() and join() to slice(), trim(), padStart() & padEnd() 🔥 My string game just levelled up. #JavaScript #CodeNewbie #webdev

Today I finally understood the difference between Maps, Sets, Arrays & Objects — and when to use each one 🔥 Dropping a quick visual in this post to show the key differences 👇 #JavaScript #webdev #CodeNewbie

Been cooking up something new! I’m designing MediCheck - a simple healthcare landing page based on everything I’ve been learning in my UI/UX class. Can’t wait to show you once it’s done #UIDesign #UXDesign #LearnInPublic

Also explored iterating over Maps. for…of with .entries(), .keys() and .values() makes going through them super straightforward 🔥 #JavaScript #CodeNewbie #webdev

Spent time with Maps in JavaScript today. Love how they let you store key/value pairs (with any type as a key!) without the quirks of plain objects 😎 #JavaScript #webdev #CodeNewbie

Tried out the for…of loop to go through arrays. No more index juggling – just clean, readable loops 👌 #JavaScript #CodeNewbie #webdev

Also played with logical assignment operators like ||=, &&= and ??=. Feels like shorthand superpowers for updating values based on conditions 🔥 #JavaScript #webdev #CodeNewbie

Finally wrapped my head around the nullish coalescing operator (??). It only kicks in for null or undefined – a tiny detail that saves me from unexpected 0s and empty strings 😅 #JavaScript #CodeNewbie #webdev
