## What it is
dlv is a 120-byte JavaScript utility for safely accessing deeply nested object properties via dot-notation key paths, with optional default values. It supports ES Modules, CommonJS, and globals.

## Use cases
- safely access nested object properties without errors
- get a value from a deep key path with a fallback default
- avoid undefined errors when traversing missing keys
- tiny dependency-free deep property getter for JavaScript

## When to choose
- you need minimal-bundle-size deep property access in JavaScript
- you want a tested, dependency-free getter with default value support

## When to avoid
- you need to set nested properties (use dset instead)
- you need TypeScript type-safe path access

## Facets

- maturity: maintenance
- function: developer-tools
- domain: developer-tools, web-development
