But when I use this code in jade

extends layout block content //p #{result} -var list=[ { username: 'rohankumar1524', name: 'Rohan Kumar' }] each item, i in list // list in place of result p test #{item.length} each role,j in item p #{role}

The output is

test rohankumar1524 Rohan Kumar which is expected

Whythis problem occurs, is any other module I have install by npm
