+# Documentation
+
+The following block should be given a js extension on extraction:
+
+```javascript
+console.log("js");
+```
+
+The following example contains the ignore attribute and will be ignored:
+
+```typescript ignore
+const value: Invalid = "ignored";
+```
+
+The following example will trigger the type-checker to fail:
+
+```typescript
+const a: string = 42;
+```
