function outerFunction(innerFunction) {
  console.log("外部函数");
  innerFunction();
}

function innerFunction() {
  console.log("内部函数");
}

outerFunction(innerFunction);

function outerFunction() {
  console.log("外部函数");
  
  return function innerFunction() {
    console.log("内部函数");
  };
}

var inner = outerFunction();
inner();

var obj = {
  outerFunction: function() {
    console.log("外部函数");
    this.innerFunction();
  },
  innerFunction: function() {
    console.log("内部函数");
  }
};

obj.outerFunction();

function outerFunction() {
  console.log("外部函数");
}

function innerFunction() {
  console.log("内部函数");
}

outerFunction.call(innerFunction);
