Answer 1

You can't append content to a script and have the browser "re-parse" the script

You can create a new script tag, add the content, and append that to the body

 <script> const a = `function amb() { console.log('hello')}`; const scr = document.createElement('script'); scr.textContent = a; document.body.append(scr); </script> <div id="a"> <button onclick="amb()"> amb </button> </div>

Answer 2

You can use eval aswell

 <script id="append_here"> // the appended function goes in this script </script> <script> a = `function amb() { console.log('hello')}`; document.getElementById("append_here").append(eval(a)); </script> <div id="a"> <button onclick="amb()">amb</button> </div>
