Javascript Standard Object - How To Return Two Elements?

Question

If I have the Standard Object

 var data = [];

 data["Name"] = ["Janet", "James", "Jean", "Joe", "John"];
 data["Number"] = [25, 22, 37, 19, 40];

Say I want the minimum number value '19'

How can I return and display the Name associated with the minimum number value? What about the Name associated with the maximum value?

Basically, how can I return two elements at once and how can I find out if they are associated with each other?

I've tried indexOf() but methods don't work properly on Standard Objects. I'm fairly new to Javascript.

EDITED: forgot the square brackets on the array...

Answer 1

Use Math.min.apply to get smallest value from array and Array#indexOf to get index of the smallest number

 var data = {}; //Initialize it as object data["Name"] = ["Janet", "James", "Jean", "Joe", "John"]; data["Number"] = [25, 22, 37, 19, 40]; var min = Math.min.apply(null, data["Number"]); console.log(min); console.log(data["Name"][data["Number"].indexOf(min)]); //-----------------------^^^^^^^^^^^^^^^^^^^^^^^^^^^To get the index of smallest number 

Answer 2

The alternative solution using ES6 Array.prototype.find() function:

// search for MAX number
var idx = data["Number"].indexOf(Math.max.apply(null, data["Number"])),
    nameWithMax = data["Name"].find((v, i) => i === idx);
console.log(nameWithMax);  // "John"
