## Annotating Return Types (EN)
## Annotation des types de retour

Because of the circular nature of Vue's declaration files, TypeScript may have difficulties inferring the types of certain methods.
For this reason, you may need to annotate the return type on methods like `render` and those in `computed`.
Du fait de la nature circulaire de la déclaration des fichiers Vue, TypeScript peut avoir des difficultés à deviner les types de certaines méthodes. Pour ces raisons, vous devriez annoter les types de retour des méthodes comme `render` et ceux dans `computed`.

```ts
import Vue, { VNode } from 'vue'

const Component = Vue.extend({
data() {
return {
msg: 'Hello'
msg: 'Bonjour'
}
},
methods: {
// need annotation due to `this` in return type
// besoin d'une annotation car `this` fait parti du type de retour
greet(): string {
return this.msg + ' world'
}
},
computed: {
// need annotation
// besoin d'une annotation
greeting(): string {
return this.greet() + '!'
}
},
// `createElement` is inferred, but `render` needs return type
// `createElement` est deviné, mais `render` à besoin d'une annotation de type de retour

If you find type inference or member completion isn't working, annotating certain methods may help address these problems.
Using the `--noImplicitAny` option will help find many of these unannotated methods.
Si vous vous apercevez que l'autocomplétion ne fonctionne pas, annoter certaines méthodes peut aider à résoudre ces problèmes. Utiliser l'option `--noImplicitAny` aidera à trouver bon nombre de ces méthodes non annotées.
