My teacher made an array in my javascript file that i am not allowed to change. I am supposed to add new objects to it trough code without touching that array.

This is what my array looks like:

const words = [{
    dutch: "vork",
    english: "Fork",
    dutchDescription: "Iets waarmee je eet dat doorgaans vier tanden heeft.",
    englishDescription: "Something you eat with that usually has four tines.",
    isknown: false
  },
  {
    dutch: "mes",
    english: "knife",
    dutchDescription: "Bestek dat snijdt.",
    englishDescription: "Cutlery that cuts.",
    isknown: false
  },
  {
    dutch: "lepel",
    english: "spoon",
    dutchDescription: "Bestek waarmee je soep eet.",
    englishDescription: "Cutlery you use to eat soup.",
    isknown: false
  }
];

I tried to make it like this:

function addCustomWord(object) {
  const words2 = [{
    dutch: "testDutch",
    english: "testEnglish",
    dutchDescription: "dutchDiscriptionTest",
    englishDescription: "englishDiscriptionTest",
    isknown: false
  }]
  words.push(words2);
}

That clearly doesn't work and i am having a hard time trying to find anything that actualy works. I have been trying very different solutions for hours and i can't find anything that works. Could someone help me with my problem?
