Editing Code folding (section)

===Collapsing metadata===
Metadata can be lengthy, and is generally less important than the data it is describing. Collapsing metadata allows one to primarily focus on the data, not the metadata. For example, a long list of [[Attribute (computing)|attributes]] in [[C Sharp (programming language)|C#]] may be manually collapsed as follows:<ref>{{Cite web |last=Rob |date=March 19, 2014 |title=Now, this is interesting, because I tend to use #region more to HIDE THE CRAP (XML documentation etc, long list of attributes etc.) making it easier to see the important code… |url=http://discourse.codinghorror.com/t/the-problem-with-code-folding/294/31 |url-status=live |archive-url=https://web.archive.org/web/20200806132848/https://discourse.codinghorror.com/t/the-problem-with-code-folding/294/31 |archive-date=Aug 6, 2020 |website=The Problem With Code Folding |publisher=Coding Horror Discussion}}</ref>
