? What is a Callback in jQuery?

A callback is a function that runs after another function finishes � it's commonly used in animations, AJAX, or events to make sure something happens in order.

? This is especially useful when you want to run code after an animation or effect finishes.

? Basic Syntax

javascript
$(selector).<div "#fadeBtn").click(function() {    $("#box").fadeOut(1000, function() {      alert("Fade out complete!");    });  });</script>

? The alert() runs after the fade out completes.

? Example 2: Chaining with Callback

javascript
$("#box").slideUp(1000, function() {  $("#box").slideDown(1000);});

? This smoothly slides the box up, then down � in perfect sequence.

? Example 3: Custom Callback Function

You can also define your callback function separately:

javascript
function showMessage() {  console.log("Animation done!");}$("#box").animate({ width: "300px" }, 800, showMessage);

?? Why Use Callbacks?

• Ensures order of execution

• Prevents unexpected behavior in animations or AJAX

• Makes your code cleaner and easier to manage
