Start by implementing a type guard before looping through all the HTML elements.
If you skip this step, querySelectorAll will return a type union of HTMLInputElement or null, causing TypeScript to throw an error. This is the default behavior of the strict checker.
let paragraphSubEl = document.querySelectorAll('.add-article__form-subtitle');
if(paragraphSubEl) {
paragraphSubEl.forEach(node => { console.log(node.firstChild.nodeValue) })
}
