unique

Remove duplicate values.

Similar: unique, [isUnique].

function unique(x, fc, fm)
// x:  a sorted array
// fc: compare function (a, b)
// fm: map function (v, i, x)

const xsortedArray = require('extra-sorted-array');

var x = [10, 20, 20, 40, 40, 80];
xsortedArray.unique(x);
// → [ 10, 20, 40, 80 ]
