Day 1 - Strengthening Fundamentals

I’m focusing on building a solid foundation. Today was all about revisiting core programming concepts in JavaScript. Problems Covered Printing numbers using loops Working with even numbers Classic FizzBuzz problem Prime number validation Code Implementation // 1. Print numbers from 1 to 100 for (let i = 1; i <= 100; i++) { console.log(i); } // 2. Print all even numbers ≤ 1000 for (let i = 2; i <= 1000; i += 2) { console.log(i); } // 3. FizzBuzz (1 to 100) for (let i = 1; i <= 100; 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); } // 4. Prime number check function isPrime(n) { if (n <= 1) return false; for (let i = 2; i < n; i++) { if (n % i === 0) return false; } return true; } console.log(isPrime(17)); // true
