+## jQuery Chaining
+jQuery chaining allows you to execute multiple methods on the same jQuery selection, all on a single line.
+
+Chaining allows us to turn multi-line statements:
+```javascript
+$('#someElement').removeClass('classA');
+$('#someElement').addClass('classB');
+```
+Into a single statement:
+```javascript
+$('#someElement').removeClass('classA').addClass('classB');
+```
+
