Showing an image or text for few seconds using javascript : <p>I am building a web app: front-end in Angular and back-end in Rails.
When users are done with filling out the application, they need to press "save" button to save the data. </p>

<p>Right now, when the user clicks the button, there is currently no feedback. When the button is clicked, I wanna show either text or image which says "Data Saved" for 2 seconds. </p>

<p>I would like to add code, but I have no idea how to even start with this. If anyone knows how to do this with Angular or Javascript, please let me know! </p>
