Day 3/30 – JavaScript Challenge #30daysOfLeetCode Solved LeetCode: To Be Or Not To Be ✅ The solution implements a custom expect function that returns an object with two methods: toBe and notToBe. These methods compare values using strict equality (===) and throw meaningful errors when conditions fail. Closures are used to retain access to the initial value, enabling clean and readable test-like behavior without global variables. ✅ All test cases passed 📌 Learning how testing utilities work internally and strengthening JavaScript fundamentals On to the next problem 💪 #30DaysOfJavaScript #JavaScript #LeetCode #ProblemSolving #LearningInPublic #CodingJourney #WebDevelopment

🚀 Day 2 of JavaScript Practice | LeetCode – 30 Days of JavaScript Today was all about understanding array transformations and callbacks in JavaScript. ✅ Problems solved today: Apply Transform Over Each Element in Array Filter Elements from Array Array Reduce Transformation 📌 Key learnings: How map, filter, and reduce work internally The importance of callbacks and accumulator logic Writing solutions without using built-in methods to strengthen fundamentals Slow progress, but solid foundations. Consistency over motivation 💪 On to Day 3 🚀 #JavaScript #LeetCode #30DaysOfJavaScript #ProblemSolving #Consistency #LearningInPublic #WebDevelopment

Day 5/30 – JavaScript Challenge #30daysOfLeetCode Solved LeetCode 2634: Filter Elements from Array using JavaScript ✅ The solution recreates the behavior of Array.filter by manually iterating through the array and applying a filtering function to each element and its index. Only values that evaluate to truthy are included in the final array, which helped reinforce concepts like callbacks, loops, and truthy vs falsy values in JavaScript. ✅ All test cases passed 📌 Strengthening JavaScript fundamentals by understanding how built-in methods work internally On to the next challenge 💪 #30DaysOfJavaScript #JavaScript #LeetCode #ProblemSolving #LearningInPublic #CodingJourney #WebDevelopment

Conditional statements are one of the most important concepts in JavaScript. They allow your code to make decisions based on different conditions using: • if • else if • else From form validation to user authentication, conditional logic exists everywhere. I teach JavaScript concepts daily and apply them using real-world projects on my YouTube channel, Code Hunter Sharath. 🎥 Playlist: 52 Weeks • 52 JavaScript Projects 👍 Follow me for daily JavaScript concepts 🔔 Subscribe to learn by building #JavaScript #LearnJavaScript #WebDevelopment #FrontendDeveloper #Coding

Day 4/30 – JavaScript Challenge #30daysOfLeetCode Solved LeetCode 2635: Apply Transform Over Each Element in Array using JavaScript ✅ The solution recreates the behavior of Array.map by iterating through the array and applying a given transformation function to each element along with its index. This helps understand how higher-order functions work internally and reinforces fundamentals like loops, function callbacks, and index-based operations. ✅ All test cases passed 📌 Focusing on mastering core JavaScript concepts without relying on built-in methods On to the next challenge 💪 #30DaysOfJavaScript #JavaScript #LeetCode #ProblemSolving #LearningInPublic #CodingJourney #WebDevelopment

I’m happy to share my JavaScript documentation on the NextZen Freedu learning platform. This document focuses on core modern JavaScript concepts, including: ✔ JavaScript Variables (var, let, const) ✔ Spread Operator ✔ Arrow Functions All topics are explained in simple and clear language, with examples and full code. #NextZenFreedu #JavaScript #WebDevelopment #LearningPlatform

Execution Context is a fundamental concept in JavaScript that dictates how our code runs. I found it interesting that understanding this can significantly enhance our grasp of variable scope and function behavior. How has a deeper understanding of execution context changed your approach to coding in JavaScript?

📘 Practising JavaScript Fundamentals – Step by Step I’ve started revising and practising JavaScript basics by solving common problems like: 🔹 String reversal 🔹 Palindrome check 🔹 Fibonacci series 🔹 Factorial calculation 🔹 Prime number check Writing solutions manually helps me understand the logic clearly instead of just memorizing syntax. Small steps, strong foundations. Consistency over perfection. 🚀 #JavaScript #LearningJourney #ProblemSolving #WebDevelopment #Consistency #SelfLearning
