Html tag not parsed

  node.js, question

Data is taken out from the database.
var data = ‘<h3>Lorem Ipsum is simply</h3>’;

After the jade template is output, the following sentence is still used: < h3>Lorem Ipsum is simply</h3 >
The h3 tag has not been parsed. Why is this so and what should I do

JadeCan filterHTMLContent, but there are still ways to directly output:

!  {data}

Supplement Ejs
