I am just starting to read the book “JavaScript: Absolute beginners guide”. But as I began to read, in the first chapter there is a tip that advises me to go to “Building your first web page” first to gain insight about what I’m about to learn. But I don’t see this chapter?

Hi @Jorge_Bibriesca - that chapter has been moved online in that edition, and you can find it here: Building Your First Interactive Web Page

That was a typo that has been corrected in future editions, so apologies for that.
