if else
- var lession = ['node','jade'] if lession if lession.length > 2 p 1 #{lession.join(', ')} else if lession.length > 1 p 2 #{lession.join(', ')} else p no lession else p no lession => <p>2 node, jade</p>
unless其实就是if的反向的判断
- var isJade = true
unless !isJade p #{lession.length} => <p>2</p>
case在jade里面不写switch case,而是写case when
- var name = 'jade' case name when 'java': p Hi java when 'jade': p Hi jade when 'node': p Hi node when 'express': p Hi express => <p>Hi jade</p>
