Day 28: Event Handling in JS
Event handling in JavaScript involves capturing and responding to user interactions such as clicks, keyboard inputs, and mouse movements. By attaching event listeners to elements, you can define functions that execute when specific events occur, enhancing interactivity.
document.addEventListener(“keydown”, function(event) {
if (event.key === “Enter”) {
alert(“Enter key pressed!”);
}
});
In this example, an event listener is added to the entire document, triggering an alert when the Enter key is pressed. Event handling is crucial for making web pages responsive to user actions.
