Basics of two-way binding

Two-way binding does two things
1. Sets a specific element property.
2. Listens for an element change event.
Angular offers a special two-way data binding syntax for this purpose, [()]. The [()] syntax combines the brackets of property binding, [], with the parentheses of event binding, ().

[( )] = BANANA IN A BOX
Visualize a banana in a box to remember that the parentheses go inside the brackets.
[(ngModel)]: Two-way binding
The NgModel directive allows you to display a data property and update that property when the user makes changes.

Import FormsModule to use ngModel
Before using the ngModel directive in a two-way data binding, you must import the FormsModule and add it to the NgModule's imports list
