The solve function provided here is designed to sort elements in an array based on their frequency and value. However, when dealing with longer input arrays, it encounters a 'Cannot read property' error which disrupts the sorting process.
To address this issue, the function was modified to be asynchronous in order to properly handle recursive operations and wait for results. Despite these changes, the function now displays a Promise {<pending>} immediately upon execution.
If you have any insights or suggestions on what might be causing this problem, your input would be greatly appreciated!
Thank you in advance!

return new Promise(resolve => {

let temp = [...result[i]];
result.splice(i, 1);
result.splice(i + 1, 0, temp);
done = false;
}

In its original form, the code displayed above worked correctly for the first call of solve but failed for subsequent calls.
function sameCountSort(arr) {
let done = true;
let result = [...arr];
for (let i = 0; i < result.length - 1; i++) {
if (result[i][1] === result[i + 1][1] && result[i][0] > result[i + 1][0]) {
let temp = [...result[i]];
result.splice(i, 1);
result.splice(i + 1, 0, temp);
done = false;
}
}
if (!done) {
sameCountSort(result);
} else {
return result;
}
}
function solve(arr){
const numberCount = {};
for (let i = 0; i < arr.length; i++) {
if (numberCount[arr[i]]) {
numberCount[arr[i]]++;
} else {
numberCount[arr[i]] = 1;
}
}
const sortedNumberCountAsArray = Object.entries(numberCount).sort((a, b) => b[1] - a[1]);
const internallySorted = sameCountSort(sortedNumberCountAsArray);
let result = [];
internallySorted.forEach((entry) => {
result = [...result, ...new Array(entry[1]).fill(parseInt(entry[0], 10))];
})
return result;
}
