I have an array like below:

 var fields = [
    {name:"mark", age:"23"}, 
    {name:"smith", age:"28"}, 
    {name:"kelvin", age:"25"}, 
    {name:"micheal", age:"22"}
];

I understand that fields will now have index/keys 0,1,2,3

How do I delete index 2 and reset keys so that we now have 0,1,2 instead of 0,1,3

If I understand this correctly, you want to remove the array element at index 2 and re-index the array so that there is no empty space. If that's the case, JavaScript has got you covered.

This will modify your original array and will remove only one element starting at index 2.

fields.splice(2,1);

Just a heads up, I meant to upvote, tag me if an edit is made and I'll reverse the downvote
@SpencerMay Just submitted an edit, should likely be shown by the time you check this notification, so you'd be able to retract it then.
@SyedM.Sannan guess it wasn't enough of an edit because it still says locked in :/ sorry
@SpencerMay I got the edit notification just half an hour ago, should work now :)
