Ce qu’il faut savoir sur React

React est une bibliothèque JavaScript open-source, développée par Meta (anciennement Facebook), utilisée pour construire des interfaces utilisateur dynamiques et réactives. Elle repose sur une approche basée sur les composants, permettant de créer des éléments réutilisables pour développer des applications web complexes. React utilise un DOM virtuel pour optimiser les performances en minimisant les mises à jour directes du DOM réel. Compatible avec de nombreux outils et frameworks, React est particulièrement apprécié pour sa flexibilité, sa gestion efficace de l'état via des librairies comme Redux, et son écosystème riche. C'est un choix privilégié pour les développeurs cherchant à créer des applications modernes et interactives.
