## What it is
Bolt for JavaScript is the official Slack framework for building Slack apps in JavaScript/TypeScript. It provides listener methods for events, actions, slash commands, shortcuts, and modals, plus support for Socket Mode and AI agent features.

## Use cases
- build a slack bot in javascript
- handle slack slash commands and buttons
- respond to slack events api messages
- create a slack ai agent with streaming replies
- build a slack app with socket mode
- add modals and interactive workflows to slack
- connect slack to an llm agent sdk

## When to choose
- you are building any custom Slack app or bot in JavaScript or TypeScript
- you want official support for the latest Slack platform features like agents, MCP, and Block Kit
- you prefer a batteries-included framework over raw Slack Web API calls

## When to avoid
- you are building Slack apps in Python, Java, or another language
- you only need simple incoming webhooks without interactivity
- you are integrating with a chat platform other than Slack
