<div id="text">Nature in the broadest sense is the physical world or universe</div>
let el = document.getElementById(text);
let eltext = el.innerText;
let final = eltext.split(" ");
let i;
for (i = 0; i < final.length; i++) {
if (final[i] === "the") {
final[i] = `<b>${final[i]}</b>`;
}
let result = (final + " ").replace(/,/g, " ");
el.innerHTML = result;
