Javascript: Sort Array of Objects by Field Value

var employees=[]
employees[0]={name:"George", age:32, retiredate:"March 12, 2014"}
employees[1]={name:"Edward", age:17, retiredate:"June 2, 2023"}
employees[2]={name:"Christine", age:58, retiredate:"December 20, 2036"}
employees[3]={name:"Sarah", age:62, retiredate:"April 30, 2020"}

- Sort by employee age

employees.sort(function(a, b){

 return a.age-b.age

})

- Sort by employee name

employees.sort(function(a, b){
 var nameA=a.name.toLowerCase(), nameB=b.name.toLowerCase()
 if (nameA < nameB) //sort string ascending
  return -1 
 if (nameA > nameB)
  return 1
 return 0 //default return value (no sorting)
})


- Sort by employee name



employees.sort(function(a, b){
 var nameA=a.name.toLowerCase(), nameB=b.name.toLowerCase()
 if (nameA < nameB) //sort string ascending
  return -1 

 if (nameA > nameB)
  return 1
 return 0 //default return value (no sorting)
})

- Sort by date (retirement date)

employees.sort(function(a, b){

 var dateA=new Date(a.retiredate), dateB=new Date(b.retiredate)

 return dateA-dateB //sort by date ascending

})
