Javascript中的函数重载 - 最佳实践

function myFunction() {
  if (arguments.length === 1 && typeof arguments[0] === 'number') {
    console.log('This is a single number parameter:', arguments[0]);
  } else if (arguments.length === 1 && typeof arguments[0] === 'string') {
    console.log('This is a single string parameter:', arguments[0]);
  } else if (arguments.length === 2 && typeof arguments[0] === 'number' && typeof arguments[1] === 'number') {
    console.log('This is two number parameters:', arguments[0], arguments[1]);
  } else {
    console.log('Invalid parameters');
  }
}

myFunction(123);
myFunction('hello');
myFunction(123, 456);
myFunction(123, 'hello');
