// output: [1, 2]
 
// Native
var arrays = [[1, 2, 3], [101, 2, 1, 10], [2, 1]];
console.log(array.reduce(function(a, b) {
  return a.filter(function(value) {
    return b.includes(value);
  });
})));
// output: [1, 2]
 
// ES6
let arrays = [[1, 2, 3], [101, 2, 1, 10], [2, 1]];
console.log(arrays.reduce((a, b) => a.filter(c => b.includes(c))));
// output: [1, 2]
