@extra-array/has-subsequence/example.js

Checks if array has a subsequence.

const array = require("extra-array");

var x = [1, 2, 3, 4];
array.hasSubsequence(x, [2, 4]);

array.hasSubsequence(x, [-2, -4]);

array.hasSubsequence(x, [-2, -4], (a, b) => Math.abs(a) - Math.abs(b));

array.hasSubsequence(x, [-2, -4], null, v => Math.abs(v));
