## Syntax

```JavaScript
// define metadata on an object or property
Reflect.defineMetadata(metadataKey, metadataValue, target);
Reflect.defineMetadata(metadataKey, metadataValue, target, propertyKey);
// check for presence of a metadata key on the prototype chain of an object or property

// check for presence of an own metadata key of an object or property
let result = Reflect.hasOwnMetadata(metadataKey, target);
let result = Reflect.hasOwnMetadata(metadataKey, target, propertyKey);
// get metadata value of a metadata key on the prototype chain of an object or property

## The Reflect Object
This section contains amendments to the Reflect object.
### Metadata Decorator Functions
A [metadata decorator function][mdf] is an anonymous built-in function that has \[\[MetadataKey\]\] and \[\[MetadataValue\]\] [internal slots][internal slot].
When a metadata decorator function <var>F</var> is called with arguments <var>target</var> and <var>propertyKey</var>, the following steps are taken:
1. [Assert][]: <var>F</var> has a \[\[MetadataKey\]\] [internal slot][] whose value is an ECMAScript language value, or **undefined**.
2. [Assert][]: <var>F</var> has a \[\[MetadataValue\]\] [internal slot][] whose value is an ECMAScript language value, or **undefined**.
3. If [Type][](<var>target</var>) is not Object, throw a **TypeError** exception.
4. Let <var>key</var> be **undefined**.
5. If <var>propertyKey</var> is not **undefined**, then
1. Set <var>key</var> to be [ToPropertyKey][](<var>propertyKey</var>).
6. [ReturnIfAbrupt][](<var>key</var>).
7. Let <var>metadataKey</var> be the value of <var>F</var>'s \[\[MetadataKey\]\] [internal slot][].
8. Let <var>metadataValue</var> be the value of <var>F</var>'s \[\[MetadataValue\]\] [internal slot][].
9. Return <var>target</var>.\[\[DefineMetadata\]\](<var>metadataKey</var>, <var>metadataValue</var>, <var>target</var>, <var>key</var>).
### Reflect.metadata ( metadataKey, metadataValue )
When the `metadata` function is called with arguments <var>metadataKey</var> and <var>metadataValue</var>, the following steps are taken:

2. Set the \[\[MetadataKey\]\] [internal slot][] of <var>decorator</var> to <var>metadataKey</var>.
3. Set the \[\[MetadataValue\]\] [internal slot][] of <var>decorator</var> to <var>metadataValue</var>.
4. return <var>decorator</var>.

2. Let <var>key</var> be **undefined**.
3. If <var>propertyKey</var> is not **undefined**, then
1. Set <var>key</var> to be [ToPropertyKey][](<var>propertyKey</var>).
2. [ReturnIfAbrupt][](<var>key</var>).
4. return <var>target</var>.\[\[DefineMetadata\]\](<var>metadataKey</var>, <var>metadataValue</var>, <var>key</var>).
### Reflect.hasMetadata ( metadataKey, target \[, propertyKey\] )
When the `hasMetadata` function is called with arguments <var>metadataKey</var>, <var>target</var>, and <var>propertyKey</var>, the following steps are taken:
1. If [Type][](<var>target</var>) is not Object, throw a **TypeError** exception.
2. Let <var>key</var> be **undefined**.
3. If <var>propertyKey</var> is not **undefined**, then
1. Set <var>key</var> to be [ToPropertyKey][](<var>propertyKey</var>).
2. [ReturnIfAbrupt][](<var>key</var>).
4. return <var>target</var>.\[\[HasMetadata\]\](<var>metadataKey</var>, <var>key</var>).
### Reflect.hasOwnMetadata ( metadataKey, target \[, propertyKey\] )
When the `hasOwnMetadata` function is called with arguments <var>metadataKey</var>, <var>target</var>, and <var>propertyKey</var>, the following steps are taken:
