var  obj1=['20','30']
 var obj2=['安卓','IOS工程师']
   function trans (arr) {
     let result = []
         arr.forEach(item => {
             item.forEach((d, i)=> {
                 let a = result[i] = result[i] || []
                  a.push(d)
          })
       })
      console.log(result)
      return result

    }
    trans([obj1,obj2])

效果如下
