Hi @horavaldesg!. I noticed this PR contains three files: variables-and-change.mdx, getting-started-with-nodejs.mdx and
simple-melody-app.mdx. Each PR should only contain the file it was opened for. The extra two files are already covered by PR #1342 and PR #1369. Could you open a new PR that contains only variables-and-change.mdx?

Let us know if you need any help.

@horavaldesg Following up on this. Were you able to review @Nwakaego-Ego's last comment?

Hi all, since @marioguzzzman reviewed one of the open PRs that had multiple files (and made comments not only on the file in the title), and aid it was ready, I merge it. After updating this branch, the other PRs are gone.

@horavaldesg if you make future PRs please do keep them separate (by using different branches for each file). But for now this PR contains 1 file, @marioguzzzman when you have time could you review please?

Thanks everyone!
