Hi Mahmoud,

You could certainly put the placeholders before the h3 element if you wanted to. The h3 element is just static text that shows the "Planet Profile" area of the web page.

In other words, it's just personal preference :).

I hope that helps! Let me know if you have any more questions!

Not a problem, Mahmoud!

I reworded my answer to make it clearer. The entire HTML string that your function is returning is the template literal. Below is the first sentence of the Template Literals MDN article:

Template literals are string literals allowing embedded expressions.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals

Therefore, the h3 element is part of the template literal. The placeholders (the ${}) are where the planet properties are inserted via interpolation. So, the h3 element is not being interpolated, it's static text in the template literal.

Does that help answer your question? Let me know if I didn't understand your question!

do u mean by static that its value doesnt change ?? thats why we enclose all of the planet properties with the dollar sign because properties can have many values ??

The template literal as a whole is dynamic because of the placeholders, the ${}, but the h3 element in particular is static since there are no placeholders in that element.

Does that help clarify?
