# Getting started

**Note:** *this feature is experimental* - users of JavaScript should expect things to break or lack complete functionality. If testing experimental software is your jam, you can use JavaScript experimentally in the app and report any bugs you find [on our GitHub](https://github.com/quadratichq/quadratic/issues) or by [reaching out to us directly](https://www.quadratichq.com/contact). 

With JavaScript in Quadratic, the world's most popular programming language meets the world's most popular tool for working with data - spreadsheets. 

## Quick start

1. Select a cell where you want to write JavaScript.
