race-as-promised

This module implements Promise.race() in a way that does not leak memory.

Rationale

The V8 Promise implementation does leak memory in many common Promise.race([...]) call cases; see e.g. nodejs/node#17469.

The V8 Promise implementation is likely not going to be fixed.

Installation

npm install race-as-promised

Usage

const race = require ("race-as-promised");
