How to remove the existing text inside <p> tag if the text is greater than 100 or specific length using javascript

is there any way to delete or replace text with (…) if the text is inside the .class p tag is greater than 100 characters?

Example I have this long text inside on the p tag:

<div class='classname'>
 <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis nibh velit, suscipit bibendum sagittis non, consequat vestibulum ante. Praesent in fermentum turpis. Nam nec erat vulputate, imperdiet mi ac, porttitor diam. Quisque posuere odio vel nulla varius dictum. Vestibulum malesuada tellus id cursus pretium. Cras volutpat, diam vel molestie bibendum, neque risus ullamcorper augue, vel convallis odio purus hendrerit quam. Mauris convallis dolor vel ex placerat, non imperdiet dolor lacinia. </p>

Expected Result:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis nibh velit, suscipit bibendum sagittis non, consequat …

>Solution :

let peles = document.querySelectorAll('.classname > p')
for(p of peles){
  let txt = p.innerText
  txt = txt.replace(txt.substring(100),'...')
  p.innerText = txt
}

<div class='classname'>
 <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis nibh velit, suscipit bibendum sagittis non, consequat vestibulum ante. Praesent in fermentum turpis. Nam nec erat vulputate, imperdiet mi ac, porttitor diam. Quisque posuere odio vel nulla varius dictum. Vestibulum malesuada tellus id cursus pretium. Cras volutpat, diam vel molestie bibendum, neque risus ullamcorper augue, vel convallis odio purus hendrerit quam. Mauris convallis dolor vel ex placerat, non imperdiet dolor lacinia. </p>
