My code runs but a bit differently. Why?

In the video he types 'list', and then it writes right away on the screen. However, I typed 'list', no reaction. After I type quit, the array prints on the screen.

By the way I don't understand why we need a while (true) here. I know 'True' is a boolean, but what condition is 'true' here to make the while loop run?

My code is below:

while (true) {
    search = prompt("Search for a product in our store. Type 'list' to show all of the produce and 'quit' to exit");
    if (search === 'quit') {
    } else if (search === 'list') {
        print(inStock.join(', '));

makes the while loop start when the document loads. A while(false) would not start on document load. I tested the code and it works fine, I re-watched the video and if you wish to re-test in the console what he does, change print() with alert().

Not sure how long it has been there, but they put an answer to your question at the top of the search.js file linked in this workspace. Had me frustrated for a minute too!
