Bonjour
J'ai recommencer le projet de zéro et à tête reposé.
Du coup le souci c'est qu'il ne faut pas mettre de majuscule à "Marked".
console . log (m arked ( texte ))
Et la sa fonctionne.
Bonne journée

Olivier Rabillon · Answer

En fait je ne peux pas utiliser la librairie marked, j'ai recommencer un projet de O en suivant la correction et des que j'arrive a marked c'est mort. j'ai utiliser la commande
npm install --save marked
puis modifier la fonction de changement du texte
const changeTextHandler = ( event ) => {
setTexte ( event . target . value );
console . log ( Marked ( texte ));
}
et a l'execution j'ai ceci
dans package.json j'ai cette ligne : "marked" : "^9.1.5" ,
Merci de votre aide
