Simple function to sort an array of objects

Question

I would like to create a  non-anonymous  function that sorts an array of objects alphabetically by the key name  I only code straight-out JavaScript so frameworks don t help me in the least   var people           name    a75    item1   false   item2   false         name    z32    item1   true    item2   false         name    e77    item1   false   item2   false

This is how simply I sort from previous examples:

if my array is items:

0: {id: 14, auctionID: 76, userID: 1, amount: 39}
1: {id: 1086, auctionID: 76, userID: 1, amount: 55}
2: {id: 1087, auctionID: 76, userID: 1, amount: 55}

I thought simply calling items.sort() would sort it it, but there was two problems: 1. Was sorting them strings 2. Was sorting them first key

This is how I modified the sort function:

for(amount in items){
if(item.hasOwnProperty(amount)){

i.sort((a, b) => a.amount - b.amount);
}
}

Array prototype sort by   function key func  reverse false       return this sort   a  b    gt    key func b  - key func a       reverse   1   -1         Then for example if we have  var arr      id  0  balls   red  8   blue  10                 id  2  balls   red  6   blue  11                 id  1  balls   red  4   blue  15         arr sort by el   gt  el id  reverse true     would result in     id  2  balls   red  6   blue  11         id  1  balls   red  4   blue  15         id  0  balls   red  8   blue  10           or  arr sort by el   gt  el balls red   el balls blue     would result in     id  2  balls   red  6   blue  11           red   blue  17     id  0  balls   red  8   blue  10           red   blue  18     id  1  balls   red  4   blue  15           red   blue  19

You can sort an array         with the  sort function   var people           name    a75    item1   false   item2   false         name    z32    item1   true    item2   false         name    e77    item1   false   item2   false       var sorted   people sort function IHaveAName a  b       non-anonymous as you ordered        return b name  lt  a name    1    if b should come earlier  push a to end            b name  gt  a name   -1    if b should come later  push a to begin            0                       a and b are equal

How about this   var people           name   a75       item1  false      item2  false          name   z32       item1  true      item2  false          name   e77       item1  false      item2  false      function sort by key array  key     return array sort function a  b       var x   a key   var y   b key     return   x  lt  y    -1     x  gt  y    1   0            people   sort by key people   name      This allows you to specify the key by which you want to sort the array so that you are not limited to a hard-coded name sort  It will work to sort any array of objects that all share the property which is used as they key  I believe that is what you were looking for   And here is a jsFiddle  http   jsfiddle net 6Dgbu
