您可以关闭并将后缀添加到值中。

const
    suffix = '*',
    getArray = (array, length) => Array
        .from(
            { length },
            (_, i) => array.map(s => s + suffix.repeat(i))
        )
        .flat(),
    result = getArray(['a', 'b', 'c'], 4);

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
