Here are the Code examples of this chapter. You can compile them online right on this web page by pressing the Typeset / Compile button. You can also edit them for testing, and compile again.
For a better view with the online compiler, I sometimes use \documentclass[border=10pt]{standalone} instead of \documentclass{article}. Instead of having a big letter/A4 page, the standalone class crops the paper to see just the visible text without an empty rest of a page.
Any question about a code example? Post it on LaTeX.org, I will answer. As forum admin I read every single question there. (profile link).

The authors of the CTAN team listed ten good reasons
for using \TeX. Among them are:
\begin{quotation}
\TeX\ has the best output. What you end with,
the symbols on the page, is as useable, and beautiful,
as a non-professional can produce.
\TeX\ knows typesetting. As those plain text samples
show, TeX's has more sophisticated typographical algorithms
such as those for making paragraphs and for hyphenating.
\TeX\ is fast. On today's machines \TeX\ is very fast.
It is easy on memory and disk space, too.
\TeX\ is stable. It is in wide use, with a long history.
It has been tested by millions of users, on demanding input.
It will never eat your document. Never.
