Erreur: vous avez à la fois un tsconfig.json et un jsconfig.json. Si vous utilisez TypeScript, veuillez supprimer votre fichier jsconfig.json.
Having both jsconfig.json and tsconfig.json is not necessary, the Typescript
Documentation cites:
The presence of a tsconfig.json file in a directory indicates that the directory
is the root of a TypeScript project.
The tsconfig.json file specifies the root files and the compiler options
required to compile the project.
JavaScript projects can use a jsconfig.json file instead, which acts almost
the same but has some JavaScript-related compiler flags enabled by default.
So in typescript is better to have just the tsconfig.json file
