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

Here's a basic example of using the _.reduceRight function from the lodash library with TypeScript:

index.ts
import * as _ from 'lodash';

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

const result = _.reduceRight<number, number>(numbers, (accumulator, value) => {
  return accumulator + value;
}, 0);

console.log(result); // Output: 15
217 chars
10 lines

In the example above, we import the lodash library and define an array of numbers. We then call the _.reduceRight function with the following parameters:

  • The array we want to reduce (numbers)
  • A function that takes two arguments: an accumulator and a value. The function returns the updated accumulator after each iteration.
  • An initial value for the accumulator.

The _.reduceRight function also takes two generics: the type of the array we're reducing (number) and the type of the accumulator (number).

The example above is just a basic example, but you can use _.reduceRight for more complex operations as well. It's a great tool for functional programming with JavaScript/TypeScript!
