- **Category:** Data Processing

- **Keywords:** has, path, lodash, object, array

## Overview

Check if a property path exists on an object or array.

**Highlights:**
- Uses lodash `_.has`
- Checks own properties only
- Returns true or false

**Example:**
- Input: `{"user":{"name":"Ada"}}`
- Path: `user.name`
- Result: `true`

## Inputs

- **Input** (textarea): Enter a JSON object or array
- **Path** (text): Property path to check

## When to use

- Validating the presence of nested keys in complex JSON data structures.
- Checking if specific configuration settings or fields exist before processing data.
- Debugging API responses to ensure required properties are present.

## How it works

- Paste your JSON object or array into the input field.
- Enter the dot-notation path you wish to verify (e.g., user.profile.id).
- Click the check button to receive a true or false result based on whether the property exists as an own property of the object.

## Use cases

- Verifying API response schemas during development.
- Filtering data objects that contain specific nested attributes.
- Ensuring configuration files contain all required keys before application startup.

## Frequently asked questions

### What does this tool check for?

It checks if a specific property path exists as an own property of the provided JSON object or array.

### Does it check inherited properties?

No, it specifically uses lodash _.has, which only checks for own properties of the object.

### What format should the path be in?

Use standard dot notation, such as 'data.items[0].name'.

### Can I check arrays?

Yes, you can check for indices or properties within arrays using the same path syntax.

### What is the output?

The tool returns a simple boolean value: true if the path exists, and false if it does not.
