Execute Only K of N JavaScript Tasks At A Time
Ever need to process thousands of tasks without overwhelming your system? Whether it's sending 1000 emails, calculating account balances, or processing bulk data — running them all at once crashes your system, but running them one-by-one wastes resources.
In this video, I'll show you 3 different approaches to execute tasks with controlled concurrency in JavaScript, and reveal why the concurrent solution is 4x faster than serial execution.
Key Concepts:
*. Serial vs Parallel vs Concurrent execution modes
*. Managing compute resources effectively
*. Avoiding the "noisy neighbor" problem
*. Promise.all vs Promise.allSettled for error handling
Perfect for intermediate to senior engineers working with Node.js, async operations, or anyone dealing with bulk processing challenges.
