This is PascalCase: SomeSymbol
This is camelCase: someSymbol
This is snake_case: some_symbol
So my questions is whether there is a widely accepted name for this: some-symbol? It's commonly used in url's.
What's the name for hyphen-separated case?

Here is a more recent discombobulation. Documentation everywhere in angular JS and Pluralsight courses and books on angular, all refer to kebab-case as snake-case, not differentiating between the two.
Its too bad caterpillar-case did not stick because snake_case and caterpillar-case are easily remembered and actually look like what they represent (if you have a good imagination).

As the character (-) is referred to as "hyphen" or "dash", it seems more natural to name this "dash-case", or "hyphen-case" (less frequently used).
As mentioned in Wikipedia, "kebab-case" is also used. Apparently (see answer) this is because the character would look like a skewer... It needs some imagination though.
Used in lodash lib for example.
Recently, "dash-case" was used by
- Angular (https://angular.io/guide/glossary#case-types)
- NPM modules

My ECMAScript proposal for String.prototype.toKebabCase.
String.prototype.toKebabCase = function () {
return this.valueOf().replace(/-/g, ' ').split('')
.reduce((str, char) => char.toUpperCase() === char ?
`${str} ${char}` :
`${str}${char}`, ''
).replace(/ * /g, ' ').trim().replace(/ /g, '-').toLowerCase();
}

I've always known it as kebab-case.
On a funny note, I've heard people call it a SCREAM-KEBAB when all the letters are capitalized.
Kebab Case Warning
I've always liked kebab-case as it seems the most readable when you need whitespace. However, some programs interpret the dash as a minus sign, and it can cause problems as what you think is a name turns into a subtraction operation.
first-second // first minus second?
ten-2 // ten minus two?
Also, some frameworks parse dashes in kebab cased property. For example, GitHub Pages uses Jekyll, and Jekyll parses any dashes it finds in an md file. For example, a file named 2020-1-2-homepage.md on GitHub Pages gets put into a folder structured as \2020\1\2\homepage.html when the site is compiled.
Snake_case vs kebab-case
A safer alternative to kebab-case is snake_case, or SCREAMING_SNAKE_CASE, as underscores cause less confusion when compared to a minus sign.
This is known as dash-case or kebab-case.
No other terms have achieved wide adoption, though there are various other coinings out there including hyphen-case, caterpillar-case, lisp-case, train-case, url-case, slug-case, and css-case.
It seems kebab-case in particular has entered the lexicon of several javascript code libraries.
