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

Checks if array starts with a prefix.

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

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

array.hasPrefix(x, [-1, -2]);

array.hasPrefix(x, [-1, -2], (a, b) => Math.abs(a) - Math.abs(b));

array.hasPrefix(x, [-1, -2], null, v => Math.abs(v));
