如何使用函数截取JS代理中的排序函数？

Question

我之前的相关问题：How do I intercept sort function within a JS proxy?

给定代理：

function sort(customSort) {
  /* Write logs */
  console.log("Intercepted sort")
  return this.sort(customSort);
}
function get( target, prop, receiver ) {
  if (prop === 'sort') {
    /* How to capture custom sort?*/
    return sort.bind(target);
  }
  console.log("Intercepted get")
  return Reflect.get( target, prop, receiver );
}
var handler = {
  get
};
var proxy = new Proxy( new Array(...[7,1,2,3,4,5]), handler );

但现在我添加了一个自定义排序函数：

console.log(proxy.sort((a,b) => .... /* e.g., a-b */))

我不明白如何捕获函数并将其传递给代理排序函数。我尝试过在get函数中捕获不同的参数，但找不到正确的参数。

解决方案类似于：How to sort only part of array? between given indexes

我返回一个访问argument[0]的函数

function sort(customSort) {
  /* Write logs */
  console.log("Intercepted sort")
  return this.sort(customSort);
}
function get( target, prop, receiver ) {
  if (prop === 'sort') {
    /* How to capture custom sort?*/
     return function(customSort) => {
       return this.sort(customSort || ((a,b) => a-b) )
     }
  }
  console.log("Intercepted get")
  return Reflect.get( target, prop, receiver );
}
