how to use the findlast function from lodash in javascript

To use the findLast function from lodash, you need to first install lodash in your project using npm. You can install it with the following command:

index.tsx
npm install lodash

2 lines

Once you have installed lodash, you can use the findLast function in your code by requiring the lodash library and calling the function like this:

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

const numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9];
const lastEvenNumber = _.findLast(numbers, function(num) {
  return num % 2 === 0;
});

console.log(lastEvenNumber); // Output: 8

In this example, we have an array of numbers and we want to find the last even number in the array using the findLast function. We pass the numbers array as the first argument to the findLast function and a callback function as the second argument. The callback function takes each element of the array as an argument and returns true if the element matches the condition we are looking for.

The findLast function starts iterating the array from the end and returns the first element for which the callback function returns true.

In this example, the findLast function will return the last even number in the array, which is 8.
