reduce-first

Return early from reduce.

.find() returns the element from an array, and .reduce() loops over every element. reduceFirst combines these to return a transformation of the first item that returns a value.

Installation

yarn add reduce-first

npm install reduce-first

API

import reduceFirst from "reduce-first";

const list = ["a", "b", "c", "d", "e"];

reduceFirst(list, (value, index, arr) => {
  if(value === "c") {
    return `found ${value}`;
  }
}); // "found c"

reduceFirst(list, (value, index, arr) => {
  if(value === "x") {
    return `found ${value}`;
  }
}); // undefined
