Question

I need to create object in javascript that allows to fetch values using keys & also iterate over keys. The primary requirement is fetching value by key but iteration is required to maintain sort order of entries by values(integer).

How do I go about creating such an object ?

Answer 1

sampleJson={
"1":"john",
"2":"johny"
}

You can iterate using for in loop

for(key in sampleJson){
//ur code
}
