This is part of package extra-array.
array.isSubsequence(x, y, [fc], [fm]);
// x: an array
// y: subsequence?
// fc: compare function (a, b)
// fm: map function (v, i, x)const array = require('extra-array');
var x = [1, 2, 3, 4];
array.isSubsequence(x, [2, 4]);
// true
array.isSubsequence(x, [-2, -4]);
// false
array.isSubsequence(x, [-2, -4], (a, b) => Math.abs(a) - Math.abs(b));
// true
array.isSubsequence(x, [-2, -4], null, v => Math.abs(v));
// true
