## What it is
Mesh is a spreadsheet-style UI wrapped around a JavaScript code editor, where grid actions are translated into code changes and vice versa. This repository is the old alpha version, superseded by Mesh v3 which uses the ngn/k formula language.

## Use cases
- edit JavaScript code through a spreadsheet grid interface
- visualize and manipulate data with rapid feedback
- replace Excel for programmatic data work
- build a loan calculator with live spreadsheet formulas
- work with nested arrays and objects in a grid UI

## When to choose
- you want spreadsheet-like visual feedback while writing JavaScript
- you find Excel too limiting for programmatic calculations
- you want to explore the original alpha of the Mesh concept

## When to avoid
- you need a stable, polished tool - this alpha has bugs and missing features like file I/O
- you want the current version of Mesh - use chrispsn/mesh-spreadsheet (v3) instead
- you need sandboxed formula evaluation

## Facets
- artifact type: application
- maturity: maintenance
- function: editor, gui, data-visualization, developer-tools
- domain: developer-tools, data-science, spreadsheets
- platform: browser, cross-platform
- tags: spreadsheet, javascript-ide, code-as-data, reactive-grid, superseded, web-server
