## parse(data, requireArray, validTypes)

> **parse**\<`T`, `K`\>(`data`, `requireArray`, `validTypes`?): [`ObservedArray`](../../Helpers/type-aliases/ObservedArray.md)\<`InstanceType`\<`K`\[`number`\]\>\> \| `null`

Parses an item or an array of items.

### Type Parameters

• **T** *extends* [`YTNode`](../../Helpers/classes/YTNode.md)

• **K** *extends* [`YTNodeConstructor`](../../Helpers/interfaces/YTNodeConstructor.md)\<`T`\>[]

### Parameters

• **data**: [`RawData`](../../APIResponseTypes/type-aliases/RawData.md)

The data to parse.

• **requireArray**: `true`

Whether the data should be parsed as an array.

• **validTypes?**: `K`

YTNode types that are allowed to be parsed.

### Returns

[`ObservedArray`](../../Helpers/type-aliases/ObservedArray.md)\<`InstanceType`\<`K`\[`number`\]\>\> \| `null`
