Some of the features of Jinja include sandboxed execution, customization of tags, filters, tests, and globals, and the ability to call functions with arguments on objects). Jinja templates use delimiters such as {{ ... }} for expressions and variables, {% ... %} for statements, {%- ... -%} for stripping whitespaces before and/or after the block, and {# ... #} for comments.
