TypeError: Unknown file extension ".ts"

When I'm trying to write normal code with TS just like we do with JS. Then everytime while running the code with ts-node im facing an issue, and I don't how to solve this.

$ ts-node index.ts
  TypeError: Unknown file extension ".ts" for E:\Typescipt project\Practice\index.ts
  at Object.getFileProtocolModuleFormat [as file:] (node:internal/modules/esm/get_format:219:9)
  at defaultGetFormat (node:internal/modules/esm/get_format:245:36)
  at defaultLoad (node:internal/modules/esm/load:120:22)
  at async ModuleLoader.loadAndTranslate (node:internal/modules/esm/loader:483:32)
  at async ModuleJob._link (node:internal/modules/esm/module_job:115:19) {
    code: 'ERR_UNKNOWN_FILE_EXTENSION'
  }

and the code I'm running (index.ts) looks like this:

type Person = {
  name: string
}

const New: Person = {
  name: "Anish"
}

console.log(New.name);

I've checked my global path and even I tried to uninstall the ts and ts-node package and reinstall along with Node. But the issue is still there!

Install the latest node version v23.6.1 and run the program again by just typing node (file).ts It Works on Runtime! - That being said you don't need to use tsx or ts-node anymore as node is able to execute typescript in the runtime environment since the latest version changes
