JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects The Student Record Search Challenge Solution

I am getting an error in chrome as soon as I preview index page.

reports.js:1 [Deprecation] Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/. d @ reports.js:1 t @ reports.js:1 c @ reports.js:1 (anonymous) @ reports.js:1 (anonymous) @ reports.js:1

and now the part of the code that prints the HTML Student Record data to the index page will only print after the prompt window is closed which means I can only see the last student I typed in.

I have added console.log commands and can see that the print function is called each time the search is executed and I have logged the results to verify the data is there and should print. However, since nothing prints until the prompt window closes ... they are never displayed ... except for the last one.

If I use a "msg += 'html' " format to append each student record - it will print all the records at one time once the prompt window is closed.

Hi there, Robin Harris! It sounds to me like you're doing great, and for the time being, I wouldn't worry much about the deprecation warning. As for the records not showing up until the window is closed, this is working as it should be and is addressed in the "Teacher's Notes". When the video was recorded, loops worked a little differently and would print while a loop was running. These days, loops wait until entirely finished before they do the printing. Again, take a look at the teacher's notes.

And yes, you would need the concatenation to print all students that match, otherwise the search result would be overwritten each time through the loop resulting in the only one being printed the last student.

Hope this helps! :sparkles:
