 title: slice

+
+The <code>slice</code> filter returns a substring, starting at the specified index. An optional second parameter can be passed to specify the length of the substring. If no second parameter is given, a substring of one character will be returned.
+
+
+| Input                                           | Output |
+|:------------------------------------------------|:-------|

+| {% raw %}`{{ "hello" | slice: 1 }}`{% endraw %} | e      |
+| {% raw %}`{{ "hello" | slice: 1, 3 }}`{% endraw %} | ell |
+
+
+If the passed index is negative, it is counted from the end of the string.
