How to disable access to js variables from console?

Question

JavaScript

Hello.
Perhaps this is superfluous, but still.
How to disable the display of variable values ​​via console.log(%var%)?
My site consists entirely of json responses from the php server, and through the developer console you can see what is in the variables.
Is there any way to protect variables from being viewed through the console?

Answer 1

Don't be fooled: the console isn't the only way to see your json.

Answer 2

(function(){
"use strict";

//приватная переменная
var a = 100500;

})()

Answer 3

JS is client-side, if that tells you anything.
And about the question itself - a local variable should not be available through the console (correct if I'm wrong), only global variables
