# Get the value at given path of an object

Follow a dot-separated path, stopping at a missing step.

Canonical: https://1loc.dev/object/get-the-value-at-given-path-of-an-object/
Version: 1.0.0
Runtime: JavaScript · Node.js 22 / modern browsers
Verification: Local fixtures; no external services
Updated: 2026-10-28

## Implementation

```javascript
function getValue({ path, object }) { return path.split('.').reduce((value, key) => (value == null ? undefined : value[key]), object) ?? null; }
```

## Input

```json
{
  "path": "delivery.recipient.status",
  "object": {
    "delivery": {
      "recipient": {
        "status": "delivered"
      }
    }
  }
}
```

## Expected output

```json
"delivered"
```

## Edge case

Input:
```json
{
  "path": "delivery.smtp.code",
  "object": {
    "delivery": {}
  }
}
```
Output:
```json
null
```

## Limits

- Missing paths return null here (undefined in the original), so the result is JSON-representable.
- The original stopped at any falsy value, so a 0 or "" on the path hid deeper keys; only null and undefined stop here.

The lab validates types and size before calling this function. Add equivalent validation at your own trust boundary.
