Can we technically implement auto suggestion feature of Google Search Engine without javascript

I read an article in : https://dev.to/vlence/do-you-really-need-javascript-3d7a

Here the author explains that google search box core functionality will work without javascript but for auto-suggestions as you type feature, javascript is required. My question is : can't we implement this feature without javascript theoretically however inefficient it is. For more elaboration on my question, please read the comment I posted on the article -- the only comment:

"I have a question out of curiosity. Say theoretically speaking, we wanted to implement Google's auto suggestion without javascript. Is it technically possible however inefficient it is??. Like on pressing a character on search box, the browser can send again request to server and server could send back the new page's html content with suggestions list. Is it theoretically possible when say for a minute we are not concerned about efficiency."
