how to use the reduceright function from lodash in javascript

To use the reduceRight function from lodash, start by installing it as a dependency in your project using a package manager like npm:

index.tsx
npm install lodash

2 lines

Then, import the function into your JavaScript code and call it with an array and a callback function:

index.tsx
import { reduceRight } from 'lodash';

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

const sum = reduceRight(numbers, (accumulator, currentValue) => {
  return accumulator + currentValue;
}, 0);

console.log(sum); // Output: 15

In this example, the reduceRight function is used to add up all the numbers in the array numbers. The callback function takes two arguments: the accumulator and the current value, and returns the updated accumulator value. Finally, the initial value of the accumulator is set to 0.

The reduceRight function iterates over the array from right to left and returns the final result of the accumulation.
