@habibasorour Please do not close this. Have someone else look at this. You have at least one typo, but there might be other insights. Then commit to the same branch and alert me.

@pearcej, this PR has been reviewed by Din Din and Hope,
We are not sure where the typo is, but if you are talking about the cut-off sentences in the comments, this is because there is a scroll bar in my build of the book that shows the whole comment within the local build itself.

Would you like me to break it into two lines?

It wasn't a typo you intruduced, but it needed to be fixed.

@habibasorour You can turn on word wrap in VSCode.

Also, you might install a code spellchecker like https://marketplace.visualstudio.com/items?itemName=streetsidesoftware.code-spell-checker.

I have fixed the issue.

[habibasorour]

ok, I will be doing that right now!
