let inputValue = document.querySelector('input').value;

let p = document.querySelector('p').textContent = inputValue;

Any time. Keep coding :)

const inputValue = document.getElementById('linkText').value;

const pSelect = document.getElementsByClassName('info')[0].textContent = inputValue;

It is because getElementsbyClassName returns an array like value a collection :D.

why wouldnt this work:

const inputValue = document.getElementById('linkText').value;

const pSelect = document.getElementsByClassName('info').textContent = inputValue;

Thxs for the reply… makes sense! Wonder if the inputValue will be formatted into an array within the ‘p’ tags

Thanks again for the quick response :)
