I can’t seem to find or notice any effect on the DOM, when i tweak the both the .Firstchild and parentNood.


#3

Please post your code.

node.firstChild
node.parentNode

#4

I had the same problem (my code is below). It took a few resets before the changes were rendered and it worked perfectly. I find that a lot of the problems in this section are much less responsive to our input compared to other lessons. Is there a reason for this?

let first = document.body.firstChild;
first.innerHTML = “I am the child!”
first.parentNode.innerHTML = ‘I am the parent and my inner HTML has been replaced!’


#5

This one is broken.
When you put the correct answer:
let first = document.body.firstChild();
first.innerHTML = “I am the child!”;

first.parentNode.innerHTML = “I am the parent and my inner HTML has been replaced!”;

The grading is messed up. It give the error: “Did you tweak the contents inside ?”
and will only accept:

let first = document.body.firstChild;
first.innerHTML = “First child”;
first.parentNode.innerHTML = “I am the parent and my inner HTML has been replaced!”;

Which is wrong the string “First child” is not mentioned in the instructions and comes from outer space.


#6
.firstChild

is not a method, but a property.
