# Concurrence et les mots-clés async et await

Cette page vise à fournir des détails sur la syntaxe `async def` pour les *fonctions de chemins* et quelques rappels sur le code asynchrone, la concurrence et le parallélisme.

Si vous utilisez des bibliothèques tierces qui nécessitent d'être appelées avec `await`, telles que :

                leftOrRight = isLeft ? 'left' : 'right',
                cal = this.container.find('.drp-calendar.'+leftOrRight);

            // Month must be Number for new moment versions
            var month = parseInt(cal.find('.monthselect').val(), 10);
            var year = cal.find('.yearselect').val();

            if (!isLeft) {
