what's the difference between `args` and `runtimeArgs`?

[mrdulin]

I modify my launch.json like this:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Current TS File",
      "type": "node",
      "request": "launch",
      "args": [
        "--nolazy",
        "-r",
        "ts-node/register",
        "${relativeFile}"
      ],
      "sourceMaps": true,
      "cwd": "${workspaceFolder}"
    }
  ]
}

It also works fine.
so, what's the difference between args and runtimeArgs?
I read official doc about debugging in vscode, did not find rumtimeArgs and protocol attributes.
