+# Boolean 
+
+Now we want to define a boolean property for our employee object - `isFullTime`
+
+```json highlightLineStart={4} 
+{
+  "name": "John Doe ",
+  "age": 25,
+  "isFullTime": true
+}
+```
+
+
+## Schema Definition
+
+We just need to define the `isFullTime` property in the schema with the type `boolean`.
+
+  ```json 
+  {
+    ...
+      "isFullTime": {
+        "type": "boolean"
+      }
+  }
+
+  ```
+add this definition to the schema which is given to you in the editor
