javascript - Replacing the last 4 characters in a string

Question

I have an element on several pages that looks like this. This is on several pages and I want to update the '2020' part to be '2021' using Javascript.

//Get string
var str = document.querySelector('#lp-pom-text-14 > p').innerHTML;

//Remove last 4 characters of the string
var strRemoved = str.slice(0, str.length - 4);

// Add 4 new characters of the string
var newString =  strRemoved + '2021';

// Set new string as innerHTML
document.querySelector('#lp-pom-text-14 > p').innerHTML = newString;

<div id="lp-pom-text-14">
  <p>Johnny's Pizza Shop. All Rights Reserved. 2020</p>
</div>
