Ou peut-être que tu as entendu dire que TypeScript pouvait aider ton code à mieux évoluer, et que tu voulais voir ce qu'il en était. Ou bien tu es un adepte du C#, et tu as pensé à essayer toute cette histoire de JavaScript. Ou tu es un programmeur fonctionnel et tu as décidé qu'il était temps de passer au niveau supérieur.
