How can I remove duplicate words from a string

Question

I am trying to remove duplicate words from the string that I stored in an object like this.

const myObj = {
  name: "rishi rishi",
  college: "mnit mnit"
};

This is my code to remove duplicate words.

const removeDuplicate = (str) => {
  return [...new Set(str.split(" "))].join(" ");
};

for (const key in myObj) {
  removeDuplicate(myObj[key]);
}

But this code doesn't remove the duplicate word, it just returns the original string.

Anyone, please help me with this.

You also have to assign the result of removeDuplicate operation otherwise the changes will be discarded. Since you are creating a change but not storing it in any container i.e. myObj[key]

myObj[key] = removeDuplicate(myObj[key]);

const myObj = {
  name: "rishi rishi",
  college: "mnit mnit",
};

const removeDuplicate = (str) => {
  return [...new Set(str.split(" "))].join(" ");
};

for (const key in myObj) {
  myObj[key] = removeDuplicate(myObj[key]);
}

console.log(myObj);
