path.join([...paths])
path.join() 方法使用特定于平台的分隔符作为定界符将所有给定的 path 片段连接在一起,然后规范化生成的路径。
零长度的 path 片段被忽略。
如果连接的路径字符串是零长度字符串,则将返回 '.',表示当前工作目录。
path.join('/foo', 'bar', 'baz/asdf', 'quux', '..');
// 返回: '/foo/bar/baz/asdf'
path.join('foo', {}, 'bar');
// 抛出 'TypeError: Path must be a string. Received {}'如果任何路径片段不是字符串,则抛出 TypeError。
The path.join() method joins all given path segments together using the
platform-specific separator as a delimiter, then normalizes the resulting path.
Zero-length path segments are ignored. If the joined path string is a
zero-length string then '.' will be returned, representing the current
working directory.
path.join('/foo', 'bar', 'baz/asdf', 'quux', '..');
// Returns: '/foo/bar/baz/asdf'
path.join('foo', {}, 'bar');
// Throws 'TypeError: Path must be a string. Received {}'A TypeError is thrown if any of the path segments is not a string.
