Find first index of value using binary search.
Similar: [includes], indexOf, [lastIndexOf].
function indexOf(x, v, i)
// x: a sorted array
// v: search value
// i: begin index [0]
const xsortedArray = require('extra-sorted-array');
var x = [10, 20, 20, 40, 40, 80];
xsortedArray.indexOf(x, 30);
// → -1
xsortedArray.indexOf(x, 40);
// → 3
