问TypeScript编译时错误

EN

function padLeft(value: string, padding: any) {
  if (typeof padding == "number") {
    return Array(padding + 1).join(" ") + value;
  }
  if (typeof padding == "string") {
    return padding + value;
  }
  throw new Error(`Expected string or number, got '${padding}'.`);
}

padLeft("Hello world", 4);

当我运行这个程序时，我得到了以下错误

F:\TypeScriptFiles\Typescript_Intersection\Progrm2.ts(8,21)：程序2.ts :\TypeScriptFiles\Typescript_Intersection>tsc TS1001:意外字符"". F:\TypeScriptFiles\Typescript_Intersection\Progrm2.ts(8,21): error TS1008: Unexpected token; 'expression' expected.

注意:我正在使用VSCode来开发这个
