Looking for best solution of HackerRank project.

[MacarioLee]

const names = ["Harry:-5", "Robbie:3", "Alexandra:3", "Michelle:4", "Malcolm", "Susan:2", "Ellen:2", "Robbie:2", "Philip:2", "Max:1", "Marlin:-4", "Michelle:-3", "Richard:5", "Malcolm", "Ellen:3", "Philip:-2", "Susan:-7", "Harry:-1", "Robbie:4", "Alexandra:-1", "Malcolm", "Richard:2", "Marilyn:-2", "Michelle:-2", "Susan:2", "Philip:1", "Richard:5","Marilyn:3", "Harry:3"];

const str = [];
const num = [];
names.map((ele) => {
str.push(ele.split(":")[0]);
num.push(ele.split(":")[1]);
})

const res = str.reduce((pre, cur, ind) => {
const cnt = (pre[cur] === undefined)?0:pre[cur];
return {
...pre,
[cur]: cnt + Number(num[ind]),
};
}, {});

for (x in res) {
if (res[x] === 0){
delete res[x];
}
}

const ans = Object.keys(res).sort().reduce((pre, cur)=> {
return {...pre, [cur]:res[cur]}
}, {});

const objTostr = (obj) => Object.entries(obj).map(([key, value]) => ${key}:${value}).join(',');

console.log(objTostr(ans));

Above is my solution,
But I have got timeout issue.

Can anybody help me?

Hi @MacarioLee,
Thanks for being a part of the GitHub Community! We're glad you're here.

I wanted to jump in and mention that if you're looking for help for this specific topic, you might want to try asking for help somewhere that focuses on the specific topic. It's definitely possible that another GitHub user might have run into this same issue and can help, but the GitHub Community on Discussions focuses primarily on topics related to GitHub itself or collaboration on project development and ideas. We want to make sure you’re getting the best support you can, but this space may not be the right place for this particular topic.

Best of luck!

That is my answer. I hope it would be help to you.

const givenArr = ["Harry:-2", "Robbie:3", "Alexandra:3", "Michelle:4", "Malcom:2", "Susan:2", "Ellen:2", "Robbie:2", "Philip:2", "Max:1", "Marilin:-4", "Michelle:-3", "Richard:5", "Malcom:3", "Ellen:3", "Philip:-2", "Susan:-7", "Harry:-1", "Robbie:4", "Alexandra:-1", "Malcom:3", "Richard:2", "Marilyn:-2", "Michelle:-2", "Susan:2", "Philip:1", "Richard:5","Marilyn:3", "Harry:3"];

let uniqueUsers = []

givenArr.sort().map(ele => {
const key = ele.split(":")[0];
const value = Number(ele.split(":")[1]);
let searchedUsers = uniqueUsers.filter(user => {
return String(Object.keys(user)) === key
}) ;
if(searchedUsers.length > 0) {
searchedUsers[0][key] += value;
}
else uniqueUsers.push({[key]: value});
});
console.log(uniqueUsers.filter(user => user[Object.keys(user)] !== 0).map(ele => ${Object.keys(ele)[0]} : ${Object.values(ele)[0]}).join(", "));

I checked, it is really awesome.
Thank you very much.
