O que costuma-se supor

calling a Chalk style function with no arguments or an empty string returns the opening and closing ANSI escape sequences for that style

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• chalk.red() with an unset argument returns an empty string with no escape codes rather than the styled empty wrapper \u001b[31m\u001b[39m
• assert chalk.red('') returns an empty string without ANSI escape codes
• assert passing explicit undefined to chalk.red(undefined) coerces to literal string '\u001b[31mundefined\u001b[39m'
• assert passing numeric 0 or boolean false coerces each value to string and applies ANSI styling
• assert multi-argument styling joins arguments with a single space delimiter before applying ANSI codes
• assert chalk.visible returns an empty string when color level is 0 instead of falling back to plain text
