Promise All with Concurrency Limit
Runs an array of async tasks with a maximum concurrency cap, preventing you from firing hundreds of requests simultaneously. Processes items in batches, moving to the next as slots free up. Essential when hitting rate-limited APIs or processing large datasets without overwhelming the server.

Promise with Timeout
Race a promise against a timeout — if the work takes longer than `ms`, reject with a timeout error. Cancels nothing on its own (use AbortController for that), but unblocks the caller.
JavaScript
Retry Promise with Backoff
Retries a Promise-returning function up to a specified number of times with configurable exponential backoff and optional jitter. Accepts a shouldRetry predicate so you can skip retries on specific error types (e.g. 401 Unauthorized). Returns the resolved value or re-throws the last error after exhausting retries.
