These lessons are covering beta software. We will make every effort we can to keep them updated and current, but while the syntax may change the concepts are what is important. If you notice an issue please post the fix or workaround in the comments if possible. Thanks!
This lesson covers using the [input] syntax to change an element property such as “hidden” or “content-editable”. Using properties eliminates the need for Angular 1’s old directives such as ng-show and ng-hide as you’re now able to directly access any property on your element.
