how to use the sortedindexof function from lodash in javascript

The sortedIndexOf function from lodash can be used to get the index at which an element should be inserted into a sorted array in order to maintain the order of the array.

Here's an example of how to use sortedIndexOf in JavaScript:

index.tsx
const _ = require('lodash');

const arr = [1, 3, 5, 7, 9];

// Get the index of 4 in the array
const index = _.sortedIndexOf(arr, 4);

console.log(index); // Output: 2
168 chars
9 lines

In this example, we first import lodash into our code. Then we define an array arr which is sorted in ascending order.

Next, we call the sortedIndexOf function and pass in the array arr as the first argument and the element we want to find the index of, which is 4, as the second argument.

The sortedIndexOf function returns the index at which 4 should be inserted into the arr array to maintain the sorted order. In this case, 4 should be inserted at index 2.

Finally, we log the index to the console.
