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

To use the sortedLastIndex function from the Lodash library in TypeScript, you'll need to first import it from the library. You can do this using:

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

Once you have imported the function, you can use it to find the index at which a value should be inserted into a sorted array, while maintaining the order of its elements. The sortedLastIndex function takes two arguments: the sorted array and the value to be inserted. For example:

index.ts
const arr = [1, 3, 5, 7, 9];
const value = 6;
const index = sortedLastIndex(arr, value);
console.log(index); // Output: 4

In the above code snippet, the sortedLastIndex function returns 4, which is the index at which the value 6 can be inserted into the arr array while maintaining its sorted order.
