+# Documentation
+
+The following block does not have a language attribute and should be ignored:
+
+```
+This is a fenced block without attributes, it's invalid and it should be ignored.
+```
+
+The following block should be given a js extension on extraction:
+
+```js
+console.log("js");
+```
+
+The following block should be given a ts extension on extraction:
+
+```ts
+console.log("ts");
+```
+
+The following example will trigger the type-checker to fail:
+
+```ts
+const a: string = 42;
+```
