Check if iterable ends with a suffix.

Alternatives: hasValue, hasPrefix, hasInfix, hasSuffix, hasSubsequence, hasPath.

function hasSuffix(x, y, fc, fm)
// x:  an iterable
// y:  seach suffix
// fc: compare function (a, b)
// fm: map function (v, i, x)

const xiterable = require('extra-iterable');

var x = [1, 2, 3, 4];
xiterable.hasSuffix(x, [3, 4]);
// → true

xiterable.hasSuffix(x, [-3, -4]);
// → false

xiterable.hasSuffix(x, [-3, -4], (a, b) => Math.abs(a) - Math.abs(b));
// → true

xiterable.hasSuffix(x, [-3, -4], null, v => Math.abs(v));
// → true
