Today I practiced a small JavaScript program to change the background color when a button is clicked. When the button is pressed, JavaScript triggers a function that changes the page’s background color using DOM manipulation. This helped me understand: ✔ Event handling ✔ onclick function ✔ DOM manipulation ✔ How JavaScript interacts with HTML & CSS Small practice, better understanding 🚀 #JavaScript #WebDevelopment #Frontend #CodingPractice #LearningJourney

Today I practiced the difference between map(), filter(), and forEach() in JavaScript. map() creates a new array by transforming each element of the original array. filter() creates a new array with elements that satisfy a specific condition. forEach() simply runs a function for each element and does not return a new array. Understanding these methods makes working with arrays much easier and cleaner. #JavaScript #WebDevelopment #ArrayMethods #LearningJourney
