Access a specific object from an array of objects

I have a variable which returns an object. This object has multiple properties, the first property is an array of more objects. I want to access this one by one using javascript and render it using html css and js.

This is my object variable (myObj).

const myJson = item.message;
const myObj = JSON.parse(myJson);
console.log(myObj);

In the first image you can see the returned object that has 2 properties.

In the second image I have expanded the first property which itself is an array of objects.

  1. I want to access these objects one by one and print them in tables using HTML, CSS and JS
  2. I want to access object property based on each property index rather than its property name eg: all the object keys will be table headers and all its values will be in data cells. I know if I want to do this without using property name eg: obj.id I have to use for loops, but I can't seem to get this correctly. Would appreciate any help.

this is what i understood from the question.

const data = {courseconfig:[{title:'title1', id:'id1'}]};

for(let i = 0; i < data.courseconfig.length; i++){
  
  const objectKeys = Object.keys(data.courseconfig[i]);
  
  for(let j = 0; j < objectKeys.length; j++)
    console.log(data.courseconfig[i][objectKeys[j]]);

}

EDIT 1: to access a property of an object which has a name you can use '.name', or ['name'].

EDIT 2: New snippet added

function extractInfo(someArray){

  for(let i = 0; i < someArray.length; i++){
  
    const objectKeys = Object.keys(someArray[i]);
  
    for(let j = 0; j < objectKeys.length; j++)
      console.log(someArray[i][objectKeys[j]]);

  }
}

const data = {courseconfig:[{title:'title1', id:'id1'}], filterconfig:[{ title:'title2', id:'id2' }]};

const dataKeys = Object.keys(data);

for(let i = 0; i < dataKeys.length; i++){
  
  if(Array.isArray(data[dataKeys[i]])){
    extractInfo(data[dataKeys[i]]);
  }

}
