Compare two entries.

Similar: compare, isEqual.

function compare(x, y, fc, fm)
// x:  entries
// y:  another entries
// fc: compare function (a, b)
// fm: map function (v, k, x)

const entries = require('extra-entries');

var x = ["a", 1], ["b", 2](/nodef/extra-entries/wiki/"a",-1],-["b",-2);
var y = ["a", 1], ["b", 2], ["c", 3](/nodef/extra-entries/wiki/"a",-1],-["b",-2],-["c",-3);
entries.compare(x, y);
// → -1

var y = ["a", 1], ["b", 2](/nodef/extra-entries/wiki/"a",-1],-["b",-2);
entries.compare(x, y);
// → 0

var y = ["a", 1], ["b", -2](/nodef/extra-entries/wiki/"a",-1],-["b",--2);
entries.compare(x, y);
// → 1

entries.compare(x, y, (a, b) => Math.abs(a) - Math.abs(b));
// → 0

entries.compare(x, y, null, v => Math.abs(v));
// → 0
