1. When we define a data binding in MXML it will use at compile time and we define a data binding in action script it will use at run time.
2. you use the bindProperty() or bindSetter() property to bind a data using action script but we have no need of these method in MXML databinding.
3. You cannot include an E4X expression in a data binding expression defined in ActionScript.
4. When we define a data binding in MXML the MXML compiler gives the better warning and error detection instead runtime data bindings
defined by the bindProperty() or bindSetter() method.
