I have an object as below:
var countryobj = {
"Canada": 10,
"Peru": 1,
"Argentina": 5,
"Colombia": 2,
"Mexico": 8
};
I want to get the first 3 smallest key value pair so that my output would be:
Peru: 1
Colombia: 2
Argentina: 5
Just get the Object.entries and sort them based on their value in ascending order, then print the first three items formatted how you like.
var countryobj = {
"Canada": 10,
"Peru": 1,
"Argentina": 5,
"Colombia": 2,
"Mexico": 8
};
const entries = Object.entries(countryobj).sort(([, a], [, b]) => a - b);
for (let i = 0; i < 3; i++) {
console.log(entries[i][0] + ": " + entries[i][1]);
}function getRange(obj, count) {
return Object.entries(obj)
.sort(([, prev], [, next]) => a - b)
.slice(0, count)
.reduce(
(result, [key]) => ({
...result,
[key]: obj[key],
}),
{},
);
}
