Why do you have JSON.stringify () your objects when sending data via AJAX?

JSON stands for javascript object designation (as I am sure you know), so why, when sending json via ajax, do you need to turn it into a string to send it? Is it just formatting, or what?

It may be in another place, if so, let me know, I will close it and translate.

Obviously, I am not looking for opinions, I would like to know the actual answer.

Just to make sure I understand, I understand what JSON.stringify () does, and its counterpart is JSON.parse (). I just want to know why use stringify.

Thanks!

If it is not a string, then it is not JSON.

JSON is a text data format. HTTP is a text communication protocol.

JSON stands for javascript object designation

JSON is based on syntax for JavaScript literals. The JavaScript object is not JSON.

AJAX is all HTTP requests, which are basically “text” requests to the server. This is the main reason you need to reinforce your object: in this way, it turns into text that can "travel" over HTTP.
