reduce with shallow copy
const vertices = new Array(100).fill(0).map((_, i) => i); vertices.reduce((list, vertex) => ({ ...list, [vertex]: new Set() }), {});
reduce without shallow copy
const vertices = new Array(100).fill(0).map((_, i) => i); vertices.reduce((list, vertex) => { list[vertex] = new Set(); return list; }, {});
foreach
const vertices = new Array(100).fill(0).map((_, i) => i); let adjacencyList = {}; vertices.forEach(vertex => { adjacencyList[vertex] = new Set(); });
