document.body.innerHTML = contentString.bold();
This will create the following HTML:
Instead of using bold() and creating HTML text directly, you should use DOM APIs such as document.createElement(). For example:
js
const contentString = "Hello, world";
const elem = document.createElement("b");
elem.innerText = contentString;
document.body.appendChild(elem);
