Input Events: change, input, keyup
Example
// Real-time character count
$("#bio").on("input", function() {
const remaining = 200 - $(this).val().length;
$("#charCount").text(remaining + " characters remaining");
});
// Trigger on blur (focus leaves)
$("#email").on("change", function() {
validateEmail($(this).val());
}); Pro Tip
Prefer "input" over "keyup" for real-time text handling — it catches paste and drag events too.
