Official statement
Deferring the loading of non-critical JavaScript until the first user interaction does not affect SEO, provided that the main content remains visible for indexing. Googlebot does not interact with the page through clicks; it only needs visible content.

TL;DR
Deferring non-critical JavaScript does not harm SEO as long as the main content remains visible. Googlebot doesn't interact with clicks, so indexing relies on the initially loaded content.
❓ Frequently Asked Questions
Le JavaScript différé affecte-t-il le crawl de Googlebot ?
Non, tant que le contenu principal est visible dès le chargement initial, le crawl reste intact.
Comment tester l'impact de mon JavaScript différé ?
Utilisez des outils comme Fetch as Google, PageSpeed Insights et Visualiser dans Webmaster Tools.
Dois-je toujours éviter d'utiliser JavaScript pour le SEO ?
Pas nécessairement. Utilisez JavaScript différemment, mais assurez-vous que le contenu essentiel reste exposé pour l'indexation par Googlebot.
