Script Preparation code:

const testPath = "http://foo.org/smth/teachers/ad0bfc84-3d16-46c3-948c-2f8d08976fcc/bar";
const userIdPathSegments = ['students', 'teachers'];
const userIdPathSegmentRegexps = [new RegExp(/students\/(?<userId>\w+)/), new RegExp(/teachers\/(?<userId>\w+)/)];

Tests:

Split
const pathParts = testPath.split('/').filter(p => p); const userIdIndex = pathParts.findIndex(p => userIdPathSegments.some(aPN => p === aPN)); if (userIdIndex >= 0 && pathParts.length > userIdIndex + 1) { pathParts[userIdIndex + 1]; }
regex
for (let i = 0; i < userIdPathSegmentRegexps.length; i++) { const match = testPath.match(userIdPathSegmentRegexps[i]); if (Array.isArray(match) && match.length == 2 && match[1].length > 0) { return match[1]; } }
