Logical operators can be used to create more complex conditions in our templates. Currently supported logical operators: and: Returns true if both the left and right operands are true. Example of use: 
{# Both are true #}
{% if true and true %}
  {# Returns true #}
{% endif %}
or: Returns true if at least one of the operands, either left or right, is true. Example of use: 
{# At least one is true #}
{% if true or false %}
  {# Returns true #}
{% endif %}
not: Negates an expression, inverting its logical value. Example of use: 
{# Negates the logical value #}
{% if not false %}
  {# Returns true #}
{% endif %}
(expr): Groups an expression to define operator precedence. Example of use: 
{# Grouping expressions #}
{% if (true or false) and true %}
{# Returns true #}
{% endif %}
