You're free to use this library, but since it was written, Underscore has started including autoescaping in its core, so this library is no longer necessary.
See http://underscorejs.org. Usage:
<%- ... %>Escaped HTML in templates
<%= ... %>Raw (unescaped) strings in templates.
In short: Just use
<%- ... %> in place of
<%= ... %> and you get escaped text with underscore.
If you want to confuse people and swap the default behaviors of these functions, continue reading. :)
Underscore Template Auto-Escape
Underscore.js is great.
However, its default template function doesn't auto-escape interpolations. Fooey!
underscore-template-autoescape.js (or the minified version) after
_.template(…) will now automatically escape values when using the
``<%= … %>
interpolation. If you wish to use the traditional, non-escaped interpolation, use<%- … %>`.
_.escapeHTML(string) will HTML escape strings.
