JavaScript Array and Object Concatenation

0ms Delay... but what about the extra arguments? 🧐 Most developers know setTimeout(callback, delay), but did you know you can pass arguments directly into the callback? #JavaScript #WebDevelopment #CodingQuiz #SoftwareEngineering #FrontendTips

Day 95 / 365 👨💻 Focused on steady React practice. 🧩 Built a small feature in an existing component 🔁 Handled state updates more smoothly ⚙️ Simplified some conditional logic 🧠 Focused on writing cleaner components #365DaysOfCode #React #JavaScript #Frontend

JavaScript: Mirror Distance Problem Day 5 👈 Goal: Find the mirror distance of a number — the absolute difference between the number and its reversed form. Approach: Reverse the given number using modulo (%) and division. Subtract the reversed number from the original. Take the absolute value to ensure a positive result. Example: Input: 123 Reversed: 321 Mirror Distance: |123 - 321| = 198 #JavaScript #TypeScript #DSA #CodingInterview #ProblemSolving #FrontendDevelopment #Developers #100DaysOfCode

I once fixed a performance issue… Didn’t change logic. Didn’t add caching. Just replaced a loop with Promise.all() Speed went 📈 Sometimes the problem isn’t scale… it’s how you write async code. #SoftwareEngineering #NodeJS #JavaScript #Performance #DevTips

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

Day 93 / 365 👨💻 Focused on refining basics through practice. 🧩 Revisited component structure and props 🔁 Tracked state changes during interactions ⚙️ Cleaned up small parts of the code 🧠 Focused on making logic easier to follow #365DaysOfCode #React #JavaScript

Day 1/30 Write a function createCounter. It should accept an initial integer init. It should return an object with three functions. The three functions are: increment() increases the current value by 1 and then returns it. decrement() reduces the current value by 1 and then returns it. reset() sets the current value to init and then returns it. #30DaysOfCode #JavaScript #LeetCode #WebDevelopment #ProgrammingChallenge #CodingLife

Day 1 — Reverse a String (JavaScript) Problem Write a function that reverses a given string. Example Input: "hello" Output: "olleh" Approach Start from the last character of the string and iterate backwards. Keep adding each character to a new string until the loop finishes. Code function reverseString(str){ let reversed = "" for(let i = str.length - 1; i >= 0; i--){ reversed += str[i] } return reversed } console.log(reverseString("hello")) What I Learned Basic string traversal and how iteration works from the end of a string. #javascript #frontenddeveloper #codingpractice #dsa
