Script Preparation code:

var dataset = [...Array(20)].map((v, idx) => idx);
var candidates = [1, 2, 5];

Tests:

lodash
var flag = candidates.length === (_.intersection(dataset, candidates)).length
es6 set
var ds = new Set(dataset); var cs = new Set(candidates); var flag = candidates.length === ([...ds].filter(v => cs.has(v))).length;
es6 loop
var flag = true; dataset.forEach((v) => { if (!candidates.includes(v)) { flag = false; } });
