DevTools detection (Chrome)

This technique takes advantage of the id attribute in the div element, and when the div element is sent to the console (such as console.log (div)), the browser automatically attempts to get the element id. If the code calls the getter method after calling console.log, the console is currently running.

The simple proof-of-concept code is as follows:

Let div = document.createElement ('div'); let loop = setInterval (() = > {console.log (div); console.clear ();}); Object.defineProperty (div, "id", {get: () = > {clearInterval (loop); alert ("DevTools detected!");}}); these are all the contents of the article "how JavaScript uses DevTools Detection".
