TypeScript - Interview Questions

A tsconfig.json file in a directory marks that directory as the root of a TypeScript project. It provides the compiler options to compile the project.

Here is a sample tsconfig.json file :

{
 "compilerOptions": {
   "module": "system",
   "noImplicitAny": true,
   "removeComments": true,
   "outFile": "../../built/local/tsc.js",
   "sourceMap": true
 },
 "include": ["src/**/*"],
 "exclude": ["node_modules", "**/*.spec.ts"]
}
