Searches a value from left. 🏃 📼 📦 🌔 📒

Alternatives: left, right, all.

iterable.search(x, v, [fc], [fm]);
// x:  an iterable
// v:  search value
// fc: compare function (a, b)
// fm: map function (v, i, x)
// --> index of value, -1 if not found

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

var x = [1, 2, 3, 2, 5];
iterable.search(x, 2);
// 1        ^

var x = [1, -2, 3, 2, 5];
iterable.search(x, 2, (a, b) => Math.abs(a) - Math.abs(b));
// 1         ^
