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

To use the findlast function from the Lodash library in TypeScript, you need to first install the Lodash library by running the following command in your project directory:

index.ts
npm install lodash
19 chars
2 lines

Once you have installed the Lodash library, you can import the findlast function in your TypeScript file using the following statement:

index.ts
import * as _ from 'lodash';
29 chars
2 lines

After importing the lodash library, you can use the findlast function in your TypeScript code as follows:

index.ts
const numbers = [1, 2, 3, 4, 5];

const lastEvenNumber = _.findLast(numbers, (n: number) => n % 2 === 0);

console.log(lastEvenNumber); // Output: 4
149 chars
6 lines

The above code uses the findlast function to find the last even number from an array of numbers. The function takes two parameters: the first parameter is the array to search, and the second parameter is a function that determines the condition to search for.

In this example, the second paramter is a function that checks if a given number is even or not. The findlast function will iterate through the array from right to left and return the last element that satisfies the condition.

I hope this helps!
