Run ejs in the browser using fetch (web server required as fetching names.ejs would cause an error with CORS)

index.html

<div id="target"></div>

index.js

// keep in mind, you'll need to import ejs somehow
fetch("names.ejs").then(async res => {
  const resText = await res.text();
  document.getElementById("target").innerHTML = ejs.render(resText, {names: ["Corey", "Austin", "Sharon", "Justin"] }); 
})

names.ejs

<% for (let name of names) { %>
    <div><%= name%></div>
<% } %>
