推荐答案

在相对 URI 中，它们之间没有区别.

In a relative URI, there is no difference between them.

不使用 ./ 将为您节省 2 个字节，因此它稍微更好.

Going without the ./ will save you 2 bytes, so it is marginally better.

在 UNIX 风格的 shell 中，关闭 ./ 将搜索 $PATH 而包括它将搜索当前目录.有些人可能出于使用 shell 的习惯而包含 ./.

In a UNIX style shell, leaving the ./ off will search $PATH while including it will search the current directory. Some people might be including the ./ out of habit from working on the shell.
