jQuery simplifies event handling for various user interactions.
$("#btn").click(function() { alert("Button Clicked!"); });
$("#box").mouseenter(function() { $(this).css("background-color", "lightblue"); }); $("#box").mouseleave(function() { $(this).css("background-color", "white"); });
$("#inputField").keypress(function(event) { console.log("Key pressed: " + event.key); });
$("#parent").on("click", "button", function() { alert("Dynamically added button clicked!"); });
