Polyfill for filter function in JavaScript

Array.prototype.myFilter = function (callbackFn, thisArg) {
  let array = this;
  let returnedArray = [];

  for (let i = 0; i < array.length; i++) {
    let callbackArguments = [array[i], i, array];

    if (thisArg) {
      if(callbackFn.call(thisArg, ...callbackArguments)){
        returnedArray.push(array[i]);
      };
    } else {
      if(callbackFn(...callbackArguments)){
        returnedArray.push(array[i]);
      };
    }
  }

  return returnedArray;
};

// Arrow function
filter((element) => {
  /* ... */
})
filter((element, index) => {
  /* ... */
})
filter((element, index, array) => {
  /* ... */
})

// Callback function
filter(callbackFn)
filter(callbackFn, thisArg)

// Inline callback function
filter(function (element) {
  /* ... */
})
filter(function (element, index) {
  /* ... */
})
filter(function (element, index, array) {
  /* ... */
})
filter(function (element, index, array) {
  /* ... */
}, thisArg)
