Hi, I am trying to display two objects at a time from an array of object when I click a button named show more items. How can I accomplish this. I have posted the codes here for anyone who can help. Also when there is no more items left, the button's innerHTML can be change to no more items to show. Thanks.

What I have tried:

HTML

<!DOCTYPE html>
<html>
<body>
<div id="output" style='padding:30px'>
<h1 id='h1'>Hello This is my text</h1>
</div>
<button id='btn' data-id='' onclick='addText()'>Add text</button>
</body>
<script type='text/javascript'>
var people = [
{id:1, name: 'Tom', job: 'Software developer', age: 33},
{id:2, name: 'Jane', job: 'Software developer', age: 36},
{id:3, name: 'Dick', job: 'Software developer', age: 38},
{id:4 name: 'Jenny', job: 'Software developer', age: 41},
{id:5, name: 'Harry', job: 'Software developer', age: 36}
{id:6, name: 'Joe', job: 'Software developer', age: 46}
];

function addText(){
for(var i = 0; i < people.length; i++){
const par = document.getElementById('h1');
const text = people[i].name + '' + people[i].job + '' people[i].age;
par.insertAdjacentHTML('afterend', text);
}
}
</script>
</html>

Hey buddy, I hope this helps I tested it out and works the way you requested... Try it out =)

<!DOCTYPE html>
<html>
<body>
  <div id="output" style='padding:30px'>
    <h1 id='h1'>Hello This is my text</h1>
  </div>
    <button id='btn' data-id=''>Add text</button>
  <script>
  var people = [
  {id:1, name: 'Tom', job: 'Software developer', age: 33},
  {id:2, name: 'Jane', job: 'Software developer', age: 36},
  {id:3, name: 'Dick', job: 'Software developer', age: 38},
  {id:4, name: 'Jenny', job: 'Software developer', age: 41},
  {id:5, name: 'Harry', job: 'Software developer', age: 36},
  {id:6, name: 'Joe', job: 'Software developer', age: 46}
  ];

  let objs = 0
  let btn = document.getElementById('btn')
  btn.addEventListener('click', () => addText())

  function addText() {
    let output = document.getElementById('output')
    let max = objs + 2
    for (let i = objs; i < people.length && i < max; i++) {
      let p = document.createElement('p')
      p.innerHTML = people[i].name + '' + people[i].job + '' + people[i].age
      output.appendChild(p)
      objs++
    }
    if (objs >= people.length - 1) {
      btn.innerHTML = 'no more items left'
    }
  }
  </script>
</body>
</html>
