Having an issue with message+=

var person = { name : 'Sarah', country : 'US', age : 35, treehouseStudent : true, skills : ['JavaScript', 'HTML', 'CSS'] };

function print(message) { var div = document.getElementById('output'); div.innerHTML = message; }

var message = '<p>Hello. My name is ' + person.name + '</p>';

//message += '<p>I live in ' person.country '</p>';

print(message);

If I run this - I get the message displayed - but if I uncomment the "message+=" line no message is displayed. In the console it says there is an: Uncaught SyntaxError: Unexpected identifier

You just forgot to concatenate.

function print(message) { console.log(message) }

var message = 'Hello. My name is ' + person.name + '';

message += 'I live in ' + person.country + '';
//                      ^                ^
print(message);
