// Check if given path has a trailing slash
hasTrailingSlash('foo/'); // -> true
hasTrailingSlash('foo'); // -> false

import { withLeadingSlash } from 'path-slashes';

// Ensure given path has a leading slash
withLeadingSlash('foo'); // -> '/foo'

import { withTrailingSlash } from 'path-slashes';

// Ensure given path has a trailing slash
withTrailingSlash('foo'); // -> 'foo/'
