There are two types of dashes. One is the "n-dash" (or "en-dash"), which takes up one space, and is most often used to hyphenate words; and the other is the "m-dash" (or "em-dash) which takes up two spaces, and is most often used to bracket off parenthetical information within a sentence, like kind of a lighter weight parentheses. Em-dashes get used a lot in novels and other published writing that is subject to correction from a professional copy editor, but very rarely in the daily typing of regular people. So now when people see it getting used they just assume it must be a clanker.

A slight correction, en-dashes are used mostly to indicate ranges like Mon–Fri. Hyphens are a separate third thing, smaller than an en-dash.

- hyphen
– en-dash
— em-dash

They get their names originally from having the same width as the letter n or m respectively in typesetting (though not all fonts follow that necessarily).

M-dashes are super useful for setting off parentheticals nicely.
