N'utilisez jamais les template strings comme outil de templating HTML.
Cela vous expose à des vulnérabilités de type XSS (Cross-Site Scripting).
/* userName is dynamically retrieved from malicious source:
* query string, api, storage etc... */
const userName = '<img src=404 onerror=alert(1)>';
document.body.innerHTML = `<span>Hi ${userName}</span>`
