Write a JavaScript function that takes an array of objects. Each object indicates a single person's information. Function name should be test().

Sample:

test([

{name:'John',age:11},{name:'Tom',age:12},{name:'Mira',age:41},

])

Output:

It will return an object from a function. That object will have two lists- Young and Old. Young will have elements with age 10-30 and Old will have elements with age 31-50. Each array will be sort by even ages people.

Sample Output:

{Young:[{name:'John',age:11},{name:'Tom',age:12}],

Old:[{name:'Mira',age:41}]

}
