Actuellement, le prototype de modifications propos\u00e9 pour inclusion dans la norme ECMAScript est en discussion pr\u00e9liminaire (Stage 0). Lors de la prochaine r\u00e9union de mars du comit\u00e9 TC39, il est pr\u00e9vu de passer \u00e0 la premi\u00e8re \u00e9tape de r\u00e9vision de la proposition en impliquant la communaut\u00e9 d'experts d'ECMA.    <\/p>\n<p>La disponibilit\u00e9 d'informations clairement d\u00e9finies sur les types permettra d'\u00e9viter de nombreuses erreurs lors du d\u00e9veloppement, d'utiliser des techniques d'optimisation suppl\u00e9mentaires, de simplifier le d\u00e9bogage et de rendre le code plus lisible et facile \u00e0 modifier et \u00e0 maintenir par d'autres d\u00e9veloppeurs. Le support des types est propos\u00e9 sous la forme d'une option facultative \u2014 les moteurs JavaScript et les environnements d'ex\u00e9cution qui ne prennent pas en charge la v\u00e9rification des types ignorent les annotations d'informations sur les types et traitent le code comme auparavant, consid\u00e9rant les informations sur les types comme des commentaires. Cependant, les outils de v\u00e9rification des types pourront identifier des erreurs li\u00e9es \u00e0 une utilisation incorrecte des types sur la base des informations disponibles.    <\/p>\n<p>En revanche, contrairement aux informations sur les types fournies via des annotations JSDoc, indiqu\u00e9es sous forme de commentaires, l'indication directe des types dans les structures de d\u00e9finition des variables rendra le code plus clair, compr\u00e9hensible et facile \u00e0 modifier. Par exemple, les environnements de d\u00e9veloppement int\u00e9gr\u00e9s prenant en charge TypeScript pourront imm\u00e9diatement signaler les erreurs dans le code JavaScript typ\u00e9 sans transformations suppl\u00e9mentaires. De plus, la prise en charge int\u00e9gr\u00e9e des types permettra d'ex\u00e9cuter des programmes \u00e9crits dans des dialectes typ\u00e9s de JavaScript, tels que TypeScript et Flow, sans
