A Slug is the unique identifying part of a web address, typically at the end of the URL. In the context of MDN, it is the portion of the URL following "<locale>/docs/". It may also just be the final component when a new document is created under a parent document; for example, this page's slug is Glossary/Slug .
A slug is a human-readable, unique identifier, used to identify a resource instead of a less human-readable identifier like an id . You use a slug when you want to refer to an item while preserving the ability to see, at a glance, what the item is.
A slug is an alternative to a name that would otherwise not be acceptable for various reasons - e.g. containing special characters, too long, mixed-case, etc. - appropriate for the target usage. What target usage means is context dependent, but could include usage in a URL or name of a file or database table for example. In the general case a slug may be composed from a combination of multiple fields; in the above case, only one field is used - title.
