I have a JSON with both subject fields and their corresponding values separately. I want to write a nested for loop that will assign the value to each subject field from below json. Right now, I am using a single for loop to loop through all the values by defining the subject field. I will be using sqlcmd-insert in each for loop after I assign the values to subjects.

for(var i = 0; i < obj.value.length; i++){
const Name= mm[i][0];
const Age= mm[i][1];
const Country= mm[i][2];
const Gender= mm[i][3];
const IsActive= mm[i][3];
}

I don't want to define variable names, instead I want it to be taken directly from JSON subject field and assign the corresponding value. I tried below nested loop but it doesn't work. How can I make this work? Please help.

for(var i = 0; i < obj.value.length; i++)
      {
        for(var j = 0; j < obj.subject.length; j++)
        {
          const obj.subject[i].field = obj.value[i][j];
        }
      }
