## What it is
lambda-view is a JavaScript code reader that parses source files into an AST and renders them in a browser with layouts optimized for reading rather than editing. It is installed via npm and launched with the `lv` command, which opens files or URLs in a local web server.

## Use cases
- read large JavaScript source files comfortably
- browse jQuery source code from a URL
- view JavaScript code with AST-aware formatting instead of plain highlighting
- read code on an iPad over LAN
- open multiple JS files at once for study

## When to choose
- you need an editor or IDE with refactoring features
- you need to read languages other than JavaScript
- you need an actively maintained tool

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: parser, developer-tools, editor
- domain: developer-tools, web-development
- platform: cli, cross-platform
- tags: code-reading, ast-viewer, javascript-reader, code-navigation, javascript, nodejs, web-server
