What's the actual behavior when extending array fields in tsconfig.json?

For example:

be-extended-tsconfig.json

{
  "compilerOptions": {
    "types": [
      "@nuxt/types"
    ]
  }
}

will this config file...

{
  "extends": "./be-extended-tsconfig.json",
  "compilerOptions": {
    "types": [
      "@nuxtjs/firebase"
    ]
  }
}

eventually resolved as this?

{
  "extends": "./be-extended-tsconfig.json",
  "compilerOptions": {
    "types": [
      "@nuxt/types",
      "@nuxtjs/firebase"
    ]
  }
}

Is there a inspect just like webpack to show the eventual merged content of tsconfig.json?
