Array of object value printing in javascript

I want to print expected output values in two loop using map, Can you please help me.

var data=[{'2021':['Q2 2021','Q3 2021','Q4 2021']},
     {'2022':['Q1 2022','Q2 2022']}
    ]
   
   data.map((obj,ind)=>{
    console.log(Object.keys(obj));
    Object.keys(obj).map((yearQuarter, i) => {
                  console.log(obj[yearQuarter]);
                  })
   })
   //getting output
   //['2022']
   //['Q1 2022', 'Q2 2022']
   //Expected Output
   //'2022'
   //'Q1 2022`
   //'Q2 2022`
   

>Solution :

We can use replace to make obj[yearQuarter] print by multiple lines

var data=[{'2021':['Q2 2021','Q3 2021','Q4 2021']},
     {'2022':['Q1 2022','Q2 2022']}
    ]

data.map((obj,ind)=>{
  console.log(Object.keys(obj)[0]);
  Object.keys(obj).map((yearQuarter, i) => {
      console.log(obj[yearQuarter].toString().replace('[]','').replaceAll(',','\n'))
   })
})
