# Flows reference

The Flows reference section provides descriptions, details, and examples for blocks, TypeScript functions, and Flows Query Language (FQL).

## Blocks reference

Learn about each block's inputs, outputs, and setup options, in the [blocks reference section](/docs/postman-flows/reference/blocks/overview/). You can also see what blocks are often used together.

## TypeScript functions

Learn how and where you can [use TypeScript](/docs/postman-flows/typescript/typescript-overview/) to enhance logic and functionality in the logic blocks of your Postman Flows.

## Flows Query Language

Learn how to use [*Flows Query Language*](/docs/postman-flows/flows-query-language/introduction-to-fql/) (FQL) in your flows to parse and transform JSON data to get the fields and structure you want. You can also discover when to use FQL as opposed to TypeScript.
