## 问题 Problem
你需要使用字符实体来替换HTML标签：
You need to replace HTML tags with named entities:
`<br/> => <br/>`
## 办法 Solution
~~~
htmlEncode = (str) ->
str.replace /[&<>"']/g, ($0) ->
"&" + {"&":"amp", "<":"lt", ">":"gt", '"':"quot", "'":"#39"}[$0] + ";"
htmlEncode('<a href="http://bn.com">Barnes & Noble</a>')
# => '<a href="http://bn.com">Barnes & Noble</a>'
~~~
