如何在运行时获取Javascript函数调用/跟踪

function foo() {
  console.trace();
}

function bar() {
  foo();
}

bar();

function foo() {
  console.log(foo.toString());
}

foo();

function foo() {
  console.log('foo called');
}

const proxy = new Proxy(foo, {
  apply(target, thisArg, argumentsList) {
    console.log('foo called with arguments:', argumentsList);
    return target.apply(thisArg, argumentsList);
  }
});

proxy();

function foo() {
  const error = new Error();
  console.log(error.stack);
}

function bar() {
  foo();
}

bar();
