下划线与驼峰相互转化？

相互转化首先想到的事用正则进行匹配

1、首先是下划线转驼峰

const lineToHump = (name = '') => {
   return name.replace(/\_(\w)/g, (all, letter) => {
      return letter.toUpperCase();
   });
};

　　console.log(lineToHump('a1_b2_c3_d4_f5'));

   //a1B2C3D4F5

2、其次驼峰转下划线

const humpToLine = (name = '') => {
   return name.replace(/([A-Z])/g, "_$1").toLowerCase();
};

　　console.log(humpToLine('aB2345C2345'));

 //a_b2345_c2345
