+# Neosync Types
+
+Neosync implements an internal type system to handle data transformations across different databases and formats. When using JavaScript transformers, these types are automatically converted to JavaScript native types and each field in the type is accessible as a property on the object.
+
+### NeosyncArray
+
+Represents array/list data types across databases. Can contain elements of any other Neosync type.
+
+```go
+type NeosyncArray struct {
+    Elements []NeosyncAdapter
+}
+```
+
+### NeosyncDateTime
+
+Handles date and time values with timezone support.
+
+```go
+type NeosyncDateTime struct {
+    Year      int
+    Month     int    // 1-12
+    Day       int    // 1-31
+    Hour      int    // 0-23
+    Minute    int    // 0-59
+    Second    int    // 0-59
+    Nano      int    // 0-999999999
+    TimeZone  string // Optional timezone
+    IsBC      bool   // For dates Before Common Era
+}
+```
+
+### Interval
+
+Represents time intervals and durations.
+
+```go
+type Interval struct {
+    Microseconds int64
+    Days         int32
+    Months       int32
+}
+```
+
+### Binary
+
+Handles binary/blob data types.
+
+```go
+type Binary struct {
+    Bytes []byte
+}
+```
+
+### Bits
+
+Represents bit string types.
+
+```go
+type Bits struct {
+    Bytes []byte
+    Len   int32
+}
+```
