Package Exports
- @extra-array/binary-search.closest
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@extra-array/binary-search.closest) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
Get index of closest value in sorted array.
Use array-binarysearch, if index of value is needed.
const binarySearch = require('@extra-array/binary-search.closest');
// binarySearch(<array>, <value>, [compare function], [this], [begin=0], [end])
// -> <index of closest value>
binarySearch([21, 42, 91, 91], 40);
// 1
binarySearch([21, 42, 91, 91], 42, null, null, 2);
// 2
binarySearch([21, 42, 91, 91], 92, null, null, 2, 4);
// 4
binarySearch([21, 42, 91, 91], 40, (a, b) => a===b? 0:(a<b? -1:1));
