- **Category:** Data Processing

- **Keywords:** forOwn, object, lodash, iterate, entries

## Overview

Iterate over own enumerable properties of an object.

**Highlights:**
- Uses lodash `_.forOwn`
- Own enumerable properties only
- Returns an ordered list of key/value entries

**Example:**
- Object: `{"a":1,"b":2}`
- Result: `[{"key":"a","value":1},{"key":"b","value":2}]`

## Inputs

- **Object** (textarea): Enter a JSON object

## When to use

- When you need to extract and list all direct properties of a JSON object for easier inspection.
- When you want to filter out inherited prototype properties and focus only on the object's own data.
- When you need to convert a raw JSON object into a structured array format for further processing or display.

## How it works

- Paste your JSON object into the input area.
- The tool applies the lodash _.forOwn function to the input.
- It isolates the object's own enumerable properties.
- The output is generated as an ordered list of key and value entries.

## Use cases

- Converting configuration objects into lists for UI rendering.
- Debugging object states by flattening them into readable key-value pairs.
- Preparing object data for mapping or transformation tasks in data pipelines.

## Frequently asked questions

### What does 'own enumerable properties' mean?

It means the tool only includes properties defined directly on the object itself, excluding any properties inherited through the prototype chain.

### Does this tool support nested objects?

The tool processes the top-level object provided. If a value within the object is another object, it will be returned as that value.

### Is the output order guaranteed?

Yes, the tool returns an ordered list of key-value entries based on the iteration of the object's own properties.

### What happens if the input is not a valid JSON object?

The tool requires a valid JSON object to function correctly; invalid syntax will prevent the iteration process.

### Can I use this for large JSON files?

This tool is designed for standard JSON objects; for extremely large datasets, ensure your input remains within the character limits of the text area.
