path.resolve總結(jié)：
path.resolve支持多路徑參數(shù)咸作。
對(duì)于給定的路徑片段横腿，是拼接處理，直至構(gòu)造出絕對(duì)路徑怕轿。
若字符以 / 開(kāi)頭，不會(huì)拼接到前面的路徑羞酗；若以 ../ 開(kāi)頭樟结，拼接前面的路徑政冻，且不含最后一節(jié)路徑；若以 ./ 開(kāi)頭 或者沒(méi)有符號(hào) 則直接拼接前面路徑伯病；

path.join總結(jié)：
path.join支持多路徑參數(shù)造烁。
對(duì)于給定的路徑片段，是拼接處理午笛，直至構(gòu)造出絕對(duì)路徑惭蟋。
相比于path.resolve，path.join更傾向于直接拼接路徑參數(shù)药磺，支持..向上跳轉(zhuǎn),若有錯(cuò)誤則報(bào)錯(cuò)告组。
