Using Google Chrome, if you console.log an object, it lets you inspect the element in the console. For example:
var a = { "foo" : "bar", "whiz" : "bang" };
console.log(a);
This prints out Object which can be inspected by clicking on arrows next to it. If however I try to log an HTMLElement:
var b = goog.dom.query('html')[0];
console.log(b);
This prints out <html></html> which can not be inspected by clicking on arrows next to it. If I want to see the JavaScript object (with its methods and fields) instead of just the DOM of the element, how would I do that?

Answer: Use console. log() or JSON. stringify() Method You can use the console. log() method, if you simply wants to know what's inside an object for debugging purpose. This method will print the object in browser console.
In the HTML DOM, the Element object represents an HTML element, like P, DIV, A, TABLE, or any other HTML element.
To change HTML element type with JavaScript, we can use the replaceWith method. For instance, we write: const parent = document. createElement("div"); const child = document.
Use console.dir:
var element = document.documentElement; // or any other element
console.log(element); // logs the expandable <html>…</html>
console.dir(element); // logs the element’s properties and values
If you’re inside the console already, you could simply type dir instead of console.dir:
dir(element); // logs the element’s properties and values
To simply list the different property names (without the values), you could use Object.keys:
Object.keys(element); // logs the element’s property names
Even though there’s no public console.keys() method, if you’re inside the console already, you could just enter:
keys(element); // logs the element’s property names
This won’t work outside the console window, though.

try this:
console.dir(element)
