path.join()和path.resolve()的区别

path.join 只是拼接path片段
path.resolve 拼接path片段后，返回一个绝对路径

举个例子：

// 区别1：
path.join('a','b') // a\b
path.resolve('a', 'b') // E:\code\node\express\a\b

// 区别2 
//  resolve识别拼接的如果首个字符是‘/’ 则把‘／’当成根目录
path.join('a', '/b') // a\b
path.resolve('a', '/b') // E:\b

__dirname是当前目录的绝对路径

。。。未完待续
