### Dump Metadata of Typed Array (Member syntax)

Return struct has a new key called `dimensions` and can also have a defined datatype. Supported datatypes are String, Numeric, Boolean, Date, Array, Struct, Query, Component, \[Component name], Binary, and Function.

```java
arr = arrayNew[ "String" ]( 1 );
writeOutput( JSONSerialize( arr.getMetadata() ) );

```

Result: {"dimensions":1,"datatype":"String","type":"synchronized"}
