Jade is an elegant templating language focused on enabling quick HTML coding. No more XML situps and percent prefixes for tags. It is HTML templating how it should be.
There is also a platform SDK to help quickly setup a Jade powered environment.
<!DOCTYPE html> <html lang="en"> <head> <title>Jade Rocks!</title> <script>console.log("hi"); </script> </head> <body> <p class="greeting">Hello, World!</p> </body> </html>
