Question

Here is my custom Object made for comparsion.. from the response i get the value and now i have to match the value with the keys in this object and return the key.

Answer 1

That could work for you:

for(key in heartRateRegular)
   if (key == value)
       return key;

The for..in clause iterates through all of the keys of the object. That’s if you want to check the value you get against the Keys of your object. If you want to check the value against the Values of your object, do the following:

for(key in heartRateRegular)
   if (heartRateRegular[key] == value)
       return key;
