binary-search-range v1.0.1

binary-search-range

Built on binary-search. Returns all indexes of items that match the comparator.

const haystack = [ 1, 3, 5, 6, 6, 6, 9, 11, 14 ]
const needle = 6
const comparator = (a, b) => a - b
binarySearchRange(haystack, needle, comparator) // => [ 3, 4, 5 ]

binarySearchRange(haystack, needle, comparator, lowIndex, highIndex)

comparator should be a function that returns 0 for matches, just like your sort function.
