how to use the reduceright function from the underscore library in javascript

The reduceRight function from the Underscore library is used to reduce a list of values into a single value by applying a function from right to left. Here's the syntax for using reduceRight:

index.tsx
_.reduceRight(list, iteratee, [memo], [context])
49 chars
2 lines
  • list: The list to be reduced.
  • iteratee: The function to apply to each element of the list.
  • memo: The initial value to be used as the accumulator.
  • context (optional): The this binding for the iteratee function.

Here's an example of using reduceRight to concatenate a list of strings from right to left:

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

const strList = ['c', 'b', 'a'];

const result = _.reduceRight(strList, (acc, curr) => {
  return acc + curr;
}, '');

console.log(result); // Output: 'abc'
191 chars
10 lines

In this example, the reduceRight function concatenates the strings from right to left, producing the output 'abc'.
