 - `<typeName>`: The name of the type, which is usually corresponds to the function name in `React.PropTypes`. However, for types define with `oneOf`, we use `"enum"` and for `oneOfType` we use `"union"`. If a custom function is provided or the type cannot be resolved to anything of `React.PropTypes`, we use `"custom"`.
 - `<typeValue>`: Some types accept parameters which define the type in more detail (such as `arrayOf`, `instanceOf`, `oneOf`, etc). Those are stored in `<typeValue>`. The data type of `<typeValue>` depends on the type definition.
 - `<flowType>`: If using flow type this property contains the parsed flow type as can be seen in the table above.
+- `<tsType>`: If using TypeScript type this property contains the parsed TypeScript type as can be seen in the table above.
