Does slugify split camelCase strings? Show me the relevant logic.

Yes, slugify splits camelCase strings by default. This is controlled by the decamelize option.

According to the documentation in [index.d.ts:L40-L50], the decamelize option is set to true by default and "Convert[s] camelcase to separate words. Internally it does fooBar → foo bar."

Here are examples from the test suite [test.js:L107-L110]:

test('decamelize option', t => {
	t.is(slugify('fooBar'), 'foo-bar');
	t.is(slugify('fooBar', {decamelize: false}), 'foobar');
});

So when you call slugify('fooBar') with default options, it returns 'foo-bar' because camelCase is split into separate words and then joined with the separator. If you disable this behavior with {decamelize: false}, you get 'foobar' instead.
