Please let me know what should I have do to add the span tag in the specific word.

>Solution :

You are not working off the text nodes when you are trying to append the element. Since you are working with innerHTML you can build the string and replace the innerHTML.

const dtag = document.querySelector('p')
const words = dtag.innerHTML.split(' ');
const mapped = words.map(word => word === 'Format' ? `<span>${word}</span>` : word);
dtag.innerHTML = mapped.join(' ');
