code box in md code example
Example 1: code blocks md
```
function test() {
console.log("notice the blank line before this function?");
}
```
Example 2: markdown code snippet
```javascript
var s = "JavaScript syntax highlighting";
alert(s);
```
```python
s = "Python syntax highlighting"
print s
```
```
No language indicated, so no syntax highlighting.
But let's throw in a <b>tag</b>.
