Using a variable as the index of an array in jade

Question

I'm trying to access an array using a variable as the index and then output it like so:

h3= users[{#id}].first_name

But I get a "SyntaxError: Unexpected token ILLEGAL" because of the #{id}. What is the correct way to do this?

You can just use id without hash or curly braces.

index.js

exports.index = function(req, res){
  res.render('index', { 
    title: 'Express',
    users: [{first_name: 'John', age: 20}, {first_name: 'Mike', age: 30}],
    id: 1
  });
};

index.jade

extends layout

block content
  h1= title
  p Welcome to #{title}
  p= users[id].first_name

@zemirco Quite old topic, but how to access users[id] if you're on the client js side script(type='text/javascript')., like it's described here? <br> I tried using !{users}[id] or users[id], but it's giving me "false true undefined" as result.
