First example of GitHub Copilot. Gets posts from the WordPress REST API and appends them to the postContainer.
// get the current site's REST API base url
const restApiBaseUrl = wpApiSettings.root;
// get the element with the class name '.posts-container' from the document
const postsContainer = document.querySelector('.posts-container');
// use restApiBaseUrl to get all of the posts from the rest api in a recursive async function. wrap the function in an IIFE.
// append the posts to the posts container as objects. add a class name to each element using the classNameBase 'shp-my-posts' and the post id.
(async function getPosts() {
// stop processing if there is no posts container
