path.resolve()和path.join()

输入

 const path0 = path.resolve(ROOT_PATH, 'docs');
 const path1 = path.resolve(ROOT_PATH, '/docs');
 const path2 = path.resolve(ROOT_PATH, './docs');
 
 const path3 = path.join(ROOT_PATH, './docs');
 const path4 = path.join(ROOT_PATH, '/docs');
 const path5 = path.join(ROOT_PATH, 'docs');

 console.log(path0);
 console.log(path1);
 console.log(path2);
 console.log(path3);
 console.log(path4);
 console.log(path5);

输出

G:\编程测试练习\11-18\docs
G:\docs
G:\编程测试练习\11-18\docs
G:\编程测试练习\11-18\docs
G:\编程测试练习\11-18\docs
G:\编程测试练习\11-18\docs

总结

• path.resolve 中 'doc' 和 './doc' 等价。
• path.join 中 'doc' 、'/doc' 和 './doc' 三者等价。
