Returns the first character or element.
Returns the first byte of a binary or the first element of a list. An empty binary is returned when the input is empty.
For example:
{{ value|first }}When the value is hello then the output is h.
Note: This function is not safe to use with multibyte character values, use with care.
For a regular list:
{{ [1,2,3]|first }}The filtered value is 1.
