7,200 PointsIs is possible to concatenating another String to InnerHTML?
Here is the code I wrote:
var message = document.querySelector("body");
message.innerHTML=<h1>1st string content</h1>;
message += "2nd string content";
console.log(message);
Intuitively, I thought this would work, but I ended up getting this [object HTMLBodyElement] Is there something wrong with my code?

Since the message variable doesn't currently contain a string, the system first reassigns it using a string that describes the body element and then concatenates the new string onto that.

7,200 PointsOk, so you mean we can not concatenates strings this way even though message.innerHTML may seem to be string but in fact it is not?

229,787 PointsThis code was not appending to message.innerHTML, which is a string. What this code was appending to is message itself, which was originally assigned to the element object.
