Guide on how to show every property of each object in an array

I have an array of words stored as objects and I am looking to showcase all the properties associated with each word. While only two words are shown here, there are actually many more in the array.

const words = [
{
word:'interrogate'
meaning:'Formally question'


},
{
word:'tiresome'
meaning:'fatiguing'


}

]

I attempted to achieve this by using a for loop but unfortunately, it didn't yield any results. The code snippet below showcases my attempt:

for(var tn= 0; tn<words.length-1; tn++){
                document.getElementById("result").innerHTML=words[tn].meaning;
            };

Despite my efforts, nothing appeared on the screen. On a side note, "result" refers to the ID of the paragraph element where I intended to display the word meanings.

All that needs to be done is as follows:

document.getElementById("output").innerHTML = `<pre> {JSON.stringify(items, null, 2)} </pre>

const items = [{
    item: 'investigate',
    definition: 'Officially question'
  },
  {
    item: 'tedious',
    definition: 'tiring'
  }
]

document.getElementById('output').innerHTML = `<pre>${JSON.stringify(items, null, 2)}</pre>`;

<div id='output'>Hello</div>

Additionally, make sure to include ',' after each property in your object. Otherwise, it will result in an error and nothing will display.

It's important to always add to an element instead of replacing it each time. To create a list of meanings, you can utilize a <ul> tag and employ the appendChild() method to append <li> elements for each meaning.

When using a for loop, ensure that the limit is set to tn < words.length, without subtracting 1 from it.

const words = [{
    word: 'interrogate',
    meaning: 'Formally question'
  },
  {
    word: 'tiresome',
    meaning: 'fatiguing'
  }
];

for (var tn = 0; tn < words.length; tn++) {
  let li = document.createElement('li');
  li.innerText = words[tn].meaning;
  document.getElementById("result").appendChild(li);
}

<ul id="result">
<ul>
