You can add a cript tag or change the contents of an existing one:
<html> <script id="script-a"></script> <body> <div> </div> <script id="script-b"> const scriptA = document.getElementById('script-a'); scriptA.innerText = "const myLog = () => console.log('BLABLA')"; myLog(); </script> </body> </html>
