how to use the sortedindex function from the lodash library in typescript

To use the sortedIndex function from the Lodash library in TypeScript, you first need to make sure you have installed the lodash library using npm or another package manager. Once you have lodash installed in your project, you can use it in your TypeScript code by importing the sortedIndex function as follows:

index.ts
import sortedIndex from 'lodash/sortedIndex';

const array = [1, 3, 5, 7];
const index = sortedIndex(array, 4);

console.log(index); // 2
138 chars
7 lines

The sortedIndex function takes two arguments: the first argument is the sorted array that you want to search, and the second argument is the value that you want to insert into the array. The function returns the index at which the value can be inserted into the array while maintaining the sorted order.

In the example above, we have an array [1, 3, 5, 7] and we want to insert the value 4 into the array while maintaining the sorted order. The sortedIndex function returns 2, which is the index at which the value 4 can be inserted in the array to maintain the sorted order.

Note that the sortedIndex function assumes that the array is already sorted. If the array is not sorted, the function may return incorrect results.
