## What it is
better-all is a TypeScript library that provides an improved Promise.all with automatic dependency optimization. Tasks are declared in an object and dependencies are expressed via a special `this.$` accessor, letting the library maximize parallelism without manual scheduling.

## Use cases
- run async tasks with dependencies in optimal parallel time
- replace nested Promise.all chains with readable task declarations
- speed up server-side data fetching with dependent async calls
- avoid manually analyzing promise dependency graphs
- get fully typed results from parallel async tasks

## When to choose
- you have multiple async tasks where some depend on others' results
- task durations vary and manual Promise.all batching becomes suboptimal
- you want readable, type-safe parallel task orchestration in JavaScript/TypeScript

## When to avoid
- your tasks are fully independent and plain Promise.all suffices
- your tasks are strictly sequential with no parallelism opportunity
- you need advanced scheduling features like retries, timeouts, or concurrency limits

## Facets
- artifact type: library
- maturity: active
- function: concurrency
- domain: developer-tools, web-development, performance
- platform: bun, cross-platform
- tags: promise, async, parallelization, dependency-graph, typescript, nodejs, deno
