- hyphen-minus. Used for joining two words together (e.g. "see-through") and as the maths "minus" symbol.

– (can type on Windows with alt+0150 on a numpad, or on Mac with option+-, or on most phones by long pressing the hyphen key) en dash. Used for ranges ("5–10 pm"), or in the place of a hyphen with compound nouns ("post–Great Migration trends" vs "post-migration trends"). For these uses, it is not surrounded by any space. It can also be used in place of an em dash, if surrounded by spaces – like this.

— (alt+0151, option+shift+-, long press) em dash. Used as a type of parenthesis, similar to the bracket (like this) or, in some cases, the comma. Used without spaces—like this.

The OP also uses what I called above an "emmm dash", playing on the name of the em dash, which is so-called because it has a width of one "em" (basically, the width of a single character in typography), and this is three ems wide. It doesn't seem to have a proper name in the typography field, though Unicode calls it "three-em dash".

I think the emmm dash's main use is probably as a dinkus. Its Wiktionary entry says it can also be used to represent censored/redacted information or duplicate authors in a bibliography.

Urban Dictionary says it is "basically used in usernames to show off to other people".

On the one hand, I agree spaces surrounding em dashes is not great.

On the other hand, the use of the rare emmm dash is cool enough to make up for it IMO.

Ah man, pic no load for me on jerboa :(
