Tag: A user can type multiple tags (separated by a “;”). Save: When clicked, it saves the photo in a database along with the tags. Load: A user can specify one or more tags. Your app will find and show the first photo that had any of those tags. When there are multiple photos matching the criteria, the App should have an UI element to show them one by one, e.g., when the user slides a slider.I need plagiarism free response only don't try to copy.
- in Mongo DB We want to add some students to our collection, but this time, we define the value for the _id field.

Define a variable named starray and add these two document to the variable. (You are storing more than one document so you need to define an array.) write the command to define the array: Now, use the starray array to insert the documents to your collection student.
