# Array `find` and Arrow Functions

`Array.prototype.find` returns the first element that matches a condition.

## Example

```ts
const parts = [
	{ type: 'year', value: '2026' },
	{ type: 'month', value: '03' },
	{ type: 'day', value: '24' },
];

const yearPart = parts.find((part) => part.type === 'year');
console.log(yearPart); // { type: 'year', value: '2026' }
```

## Arrow Function Syntax

```ts
(part) => part.type === 'year'
```

- `(part)`: parameter.
- `=>`: arrow token.
- `part.type === 'year'`: expression result (`true` or `false`).

If no item matches, `find` returns `undefined`.

## Python Comparison

Similar to:

```py
year_part = next((p for p in parts if p['type'] == 'year'), None)
```
