"JS Scopes & Closures: A Humorous Guide"

💻 Exploring JavaScript Operators and Functions! 🚀 Today I practiced different types of operators and functions in JavaScript, including: ✨ Arithmetic Operators ( + , - , * , % ) ✨ Logical Operators ( && , || , ! ) ✨ String Concatenation ✨ Custom Functions for addition, subtraction, multiplication, and division This helped me understand how JavaScript performs calculations, comparisons, and combines strings — all fundamental skills for any developer! 🧠 Every line of code teaches something new. #JavaScript #WebDevelopment #CodingJourney #LearnToCode #Programming #JSBasics

Day 15 of #30DaysOfJavaScript on LeetCode Today's Challenge: 2725 — Interval Cancellation This problem focused on mastering repeated asynchronous execution in JavaScript — specifically, how to repeatedly run a function using setInterval() and stop it with clearInterval(). Here’s my solution 👇 var cancellable = function(fn, args, t) { fn(...args); let timer = setInterval(() => fn(...args), t); let cancelFn = () => clearInterval(timer); return cancelFn; }; This exercise helped me understand how interval-based scheduling works and how to control execution flow by canceling ongoing intervals a common pattern in real-world applications like periodic data fetching or live updates.

JavaScript Quirks Every Developer Should Know Understanding these "funny" behaviors isn't just entertaining it's essential for writing better code: - - Why [] == ![] is true (type coercion) - Why 0.1 + 0.2 ≠ 0.3 (floating-point precision) - Why sort() doesn't work as expected (alphabetical default) These quirks teach us valuable lessons about JavaScript's underlying mechanics.

🚀 Learning JavaScript: Practicing “for loops”! Today, I worked on different examples using for loops in JavaScript — a powerful tool for repeating tasks efficiently. Here’s what I explored 👇 💡 Tasks I completed: 1️⃣ Printed even numbers from 2 to 20 2️⃣ Printed odd numbers from 1 to 19 3️⃣ Calculated the square of numbers from 1 to 5 4️⃣ Found the sum of numbers from 1 to 10 5️⃣ Calculated the product of numbers from 1 to 5 6️⃣ Printed the cube of numbers from 1 to 5 7️⃣ Displayed numbers from -5 to 5 🧠 This exercise helped me understand how iteration, increment, and logical conditions work together in JavaScript loops. 🌱 Every small project like this helps strengthen my programming logic and problem-solving skills! #JavaScript #CodingJourney #ForLoop #WebDevelopment #100DaysOfCode #FrontendDevelopment #LearnToCode

🎯 Learning JavaScript Loops: While Loop Practice! Today, I practiced using while loops in JavaScript — one of the fundamental concepts in programming logic. Here’s what I built 👇 💡 Tasks I implemented: 1️⃣ Print numbers from 1 to 10 using a while loop. 2️⃣ Calculate the sum of numbers from 1 to 50. 3️⃣ Print numbers from 20 down to 1 in descending order. 4️⃣ Generate the multiplication table of 7 (from 1 × 7 to 10 × 7). 🧠 Each task helped me strengthen my understanding of loop conditions, increment/decrement operations, and logic flow in JavaScript. 🚀 Small steps like this make a big difference when learning to think like a developer. If you’re also learning JavaScript, try writing your own variations of these loops — it’s great practice! #JavaScript #WebDevelopment #CodingJourney #WhileLoop #LearnToCode #100DaysOfCode #FrontendDevelopment

Tired of JavaScript fundamentals feeling fuzzy? 🤯 If concepts like Hoisting, Closures, and Prototypes slow you down, you need a clearer reference. I've distilled the core structure rules of the language into Cheat Sheet Part 1: JavaScript Static Core for developers. Quickly Master: - Scope & TDZ: Variable boundaries (let/const vs var). - Hoisting Logic: What the engine really moves. - Closures: How functions create private memory. - Prototypes: The true foundation of JS inheritance.

Day 12 of #30DaysOfJavaScript on LeetCode Today's Challenge: 2723 — Add Two Promises Today’s problem was all about working with asynchronous operations in JavaScript — specifically how to handle multiple promises efficiently. Here’s my solution 👇 var addTwoPromises = async function(promise1, promise2) { const [a, b] = await Promise.all([promise1, promise2]); return a + b; }; This challenge reinforced how Promise.all() allows us to run promises in parallel, waiting for all of them to resolve before proceeding — a key concept in optimizing asynchronous workflows. It’s a clean and elegant way to handle multiple async tasks without unnecessary delays.

🚀 Day 81 of #100DaysOfCode Today I learned how to create object literals in JavaScript. An object literal lets you store related data as key-value pairs inside curly braces. For example: const car = { brand: "Toyota", year: 2020, color: "red" }; This way, you can easily organize, access, and update complex data as one unit. Object literals are foundational for structuring real-world information in your programs. #JavaScript #ObjectLiterals #Programming #100DaysOfCode

Day 9 of #30DaysOfJavaScript on LeetCode Today's challenge: 2703 — Return Length of Arguments Passed The task was to write a function that returns the number of arguments passed to it — a simple yet elegant problem to explore rest parameters in JavaScript. Here’s my solution 👇 var argumentsLength = function(...args) { return args.length; }; It’s a short problem but a great reminder that even small concepts like this are essential for mastering function flexibility in JavaScript!

#100DaysOfCode challenge by learning programming with #JavaScript and #React with #TreeHouse Day 3- learned about strings, how to take in user inputs, how to combine them with other lines of strings (string concatenation!), and ways to make the code more readable overall. I found out very quickly that it can get very messy, very easily 😅 I've run into to some issues following along with the lessons and my biggest issue is misspellings (syntax errors). I'm just glad the JavaScript console points you to which lines have an issue. It might only show you one error line at a time but it's better than nothing! It's definitely a lot to take in so I understand why it's recommended to not overwhelm yourself in the beginning and just taking it slow and one day at a time.
