l = [[1, 2], [2, 3], [3, 4]]

console.log(l.includes([2, 3]))

  • Generic object equality is defined as the objects reside in the same space in memory. You have two different arrays. They do not reside in the same memory space. Commented Jun 8, 2020 at 14:45

  • toSearch=[1,2];l.some(k=>k.every(p=>toSearch.includes(p))) Commented Jun 8, 2020 at 14:46
  • @gorak That would also match [1, 2, 9] or [2, 1] Commented Jun 8, 2020 at 14:50
  • @Ivar if so then we can match it by taking stringify of it. Commented Jun 8, 2020 at 14:55
