Benchmark Run Result for: reduce/concat vs flatMap v2

Test name	Executions per second
reduce/concat	1196939.0 Ops/sec
flatMap	562584.7 Ops/sec

Script Preparation code:

var server = {
	routes: [
      ['v1', [{ url: 'v1' }]],
      ['v2', [{ url: 'v2' }]]
    ]
}

Tests:

reduce/concat
const routes = Array.from(server.routes).reduce((routes, [_, route]) => { return routes.concat(route); }, []);
flatMap
const routes = Array.from(server.routes).flatMap((routes) => { const [_, route] = routes; return route; });
