  1. padStr为空字符串时会引起越界报错。(我看js在填充空字符串时不填充)
  2. strings.Repeat(padStr, size-len1) 可能造成巨大浪费。例如 字符串 Hello后补充 World 到 100字符,World会Repeat为 5*(100-5)=475个字符。

例如

func PadEnd(source string, size int, padStr string) string {
	len1 := len(source)
	len2 := len(padStr)

	if len1 >= size || padStr == "" {
		return source
	}

	if len1+len2 >= size {
		return source + padStr[:size-len1]
	}

	fill := strings.Repeat(padStr, (size-len1)/len2+1)[:size-len1]
	return source + fill[:size-len1]
}

v2分支已修复,下个版本会发布。
