Certainly! Here's a README.md file for the provided binary search function:

Binary Search Function

This is a JavaScript implementation of the binary search algorithm. Binary search is an efficient algorithm for finding the position of a target value within a sorted array.

Usage

const ut = require("pkg-binery-search");

const array = [1, 3, 5, 7, 9, 11, 13, 15];
const target = 7;

const index = ut.binarySearch(array, target);
console.log("Index of target:", index);

Function Signature

const binarySearch = (array, target) => {
    // Implementation here
};

Parameters

• array: A sorted array of elements. The binary search function assumes that the array is sorted in ascending order.
• target: The value to be searched in the array.

Return Value

• If the target is found in the array, the function returns the index of the target.
• If the target is not found in the array, the function returns the index where the target should be inserted to maintain the sorted order.

Example

For the given array [1, 3, 5, 7, 9, 11, 13, 15] and target 7, the function will return 3, as 7 is found at index 3 in the array.
