I have several variables with some values assigned. For ex:
Gain_weight = 0.01 Gain_weather = 0.02
and some more like this. Now I want to get the variable name with highest value assigned.
When I do something like this It returns the value not the name.
var rootNode = Math.max(Gain_weight,Gain_smoking,Gain_exercising,Gain_foodhabits,Gain_parent_heartattack,
Gain_alcohol,Gain_occupation,Gain_workinghrs);
So instead of value how can I get the highest value assigned string?
After checking this question it seems it may not be possible to get the name.
A way around can be either using an object or a associate array with name as same of variable name and it's value as the variable value
Hope this snippet will help to understand
// Array with name value pair
var _myDemoArray = [
{name:'Gain_weight',
value:0.01},
{name:'Gain_weather',
value:0.02}]
// sort the array in descending order to get the element with maximum value.
var _getSortedElem = _myDemoArray.sort(function(a,b){
return b.value -a.value;
});
// The first element of this sorted array will have element with maximum value
console.log(_getSortedElem[0].name);
