💼 JavaScript Coding Interview Questions for Freshers 🚀 Crack your next tech interview with these essential JS problems—logic + code explained clearly! Whether you're preparing for your first role or a coding bootcamp interview, these questions are frequently asked and test your core logic-building skills. --- 🔹 1️⃣ Reverse a String (Without Built-in Methods) 👨‍💻 Use a loop to reverse manually: function reverseString(str) { let reversed = ''; for (let i = str.length - 1; i >= 0; i--) { reversed += str[i]; } return reversed; } --- 🔹 2️⃣ Find the Missing Number (1 to N Sequence) 👨‍💻 Use the sum formula and subtract array values: function findMissing(arr, n) { let sum = (n * (n + 1)) / 2; for (let num of arr) { sum -= num; } return sum; } --- 🔹 3️⃣ Check if a Number is Prime 👨‍💻 Efficient method with loop till √n: function isPrime(num) { if (num <= 1) return false; for (let i = 2; i * i <= num; i++) { if (num % i === 0) return false; } return true; } --- 🔹 4️⃣ First Non-Repeating Character in a String 👨‍💻 Use an object to count character frequencies: function firstUniqueChar(str) { const count = {}; for (let char of str) { count[char] = (count[char] || 0) + 1; } for (let char of str) { if (count[char] === 1) return char; } return null; } --- 🔹 5️⃣ Implement a Basic LRU Cache 👨‍💻 Using Map() to manage key order and size: class LRUCache { constructor(capacity) { this.capacity = capacity; this.cache = new Map(); } get(key) { if (!this.cache.has(key)) return -1; const value = this.cache.get(key); this.cache.delete(key); this.cache.set(key, value); // Move to end (recently used) return value; } put(key, value) { if (this.cache.has(key)) this.cache.delete(key); if (this.cache.size >= this.capacity) { const firstKey = this.cache.keys().next().value; this.cache.delete(firstKey); } this.cache.set(key, value); } } --- 💡 Pro Tip: 📌 Practice each question with variations 📌 Focus on clean logic and explaining your approach out loud 📌 Use platforms like LeetCode, CodeWars, and JSFiddle for hands-on practice --- 💬 Preparing for your first JavaScript interview?

JavaScript Coding Interview Questions – Part 2 🧠🔥 Master these classic problems for your next tech interview! These challenges are common in JavaScript interviews and great for sharpening your problem-solving skills. Let’s dive into more must-know examples 👇 --- 🔹 6️⃣ Check for Palindrome (Two Pointers) ✅ Efficient method without reversing the string function isPalindrome(str) { let left = 0, right = str.length - 1; while (left < right) { if (str[left] !== str[right]) return false; left++; right--; } return true; } --- 🔹 7️⃣ FizzBuzz from 1 to N ✅ Classic logic test—don’t overthink it function fizzBuzz(n) { for (let i = 1; i <= n; i++) { if (i % 15 === 0) console.log("FizzBuzz"); else if (i % 3 === 0) console.log("Fizz"); else if (i % 5 === 0) console.log("Buzz"); else console.log(i); } } --- 🔹 8️⃣ Flatten a Nested Array ✅ Recursively flatten arrays of any depth function flatten(arr) { return arr.reduce((flat, item) => flat.concat(Array.isArray(item) ? flatten(item) : item), []); } --- 🔹 9️⃣ Count Vowels in a String ✅ Use regex to match all vowels function countVowels(str) { return (str.match(/[aeiou]/gi) || []).length; } --- 🔹 🔟 Find Factorial Using Recursion ✅ Test your understanding of recursion function factorial(n) { if (n <= 1) return 1; return n * factorial(n - 1); } --- 💡 Pro Tip: ➡️ Always explain your thought process when solving these in interviews ➡️ Practice with variations: edge cases, input validation, and optimization 💬 Preparing for coding rounds?
