Array - JavaScript | MDN
July 28, 2026 - The Array object, as with arrays in other programming languages, enables storing a collection of multiple items under a single variable name, and has members for performing common array operations. In JavaScript, arrays aren't primitives but are instead Array objects with the following core ...

r/javascript on Reddit: Array of objects, best way to do it.
November 9, 2018 -
So I made an array with objects. For example here, let's use people
var people = [
{
id: 0,
name: "John Doe",
age: 47
},
{
id: 1,
name: "Jane Doe",
age: 88
},
{
id: 2,
name: "Mason Louis",
age: 17
}
];
so now I can use people[1].name etc for accessing the data on each of these people. Someone just saw my code and said "That looks like total S**T".
What is the proper way to do this? I was thinking this way was fine, especially since it resembles JSON
EDIT: Would it be better to create a constructor and fill an array with instances?

IMO, when people say "Your code looks like shit" and don't offer to help improve it, their opinion doesn't mean much. They aren't trying to help you, they're trying to bolster their own ego.

Relying on array order to manually access objects from a hand-written store is not very simple nor stable. The example in the OP is too abstract to give precise advice, but in general, I would make this a nested object literal instead, using your id as the key for each child object. Like this: const people = { 49593: { // person id // name, age, etc. } }; If you're accessing the elements of the array manually already, then perhaps using the ID to do it would be slightly more descriptive: people["49593"].name

Objects vs Arrays
Do you have one thing with multiple properties or do you have multiple things? The answer to this determines which you use. This is a good way to represent a dog (leaving Class aside) const dog = { name: 'Spot', age: 3, speak() { alert('woof'); } } This is a bad way to represent a dog const dog = [ 'Spot', 3, () => alert('woof'), ]; Why? console.log(dog.name); dog.speak(); Is much easier to understand than console.log(dog[0]); dog[2](); Besides just being hard to read, if your array ever goes out of order, all your code will break This is a good way to represent a list of dogs: const doggyDayCare = [ dog1, dog2, dog3, dog4, dog5, ]; This is a bad way to represent a list of dogs: const doggyDayCare = { dog1: dog1, dog2: dog2, dog3: dog3, dog4: dog4, dog5: dog5, } While you can do this, it's a lot harder to sort your dogs, find them, add to them, etc. Lets say I want all puppies const puppies = doggyDayCare.filter(dog => dog.age < 1); This gives me a new array of puppies. Could you do this with an object? Yes, but only by turning it into an array first, filtering down, then reducing back to an object. And it's ugly. const puppies = Object.entries(doggyDayCare) .filter(([key, dog]) => dog.age < 1) .reduce((previous, current) => { const result = { ...previous, }; result[current[0]] = current[1]; return result; }, {}); It is possible, but it is a bad idea. Adding a dog to an array is easy: doggyDayCare.push(newDog); How do you add a dog to an object? You have to make sure there already isn't a property with the same name for the given dog, or you'll replace it. You end up with another bit of ugly code to try to safely add a new property. So, if you have one thing with multiple properties, use an object, if you have multiple things, use an array. More on reddit.com

Data Structures: Objects and Arrays :: Eloquent JavaScript
Most values in JavaScript have properties, with the exceptions being null and undefined. Properties are accessed using value.prop or value["prop"]. Objects tend to use names for their properties and store more or less a fixed set of them. Arrays, on the other hand, usually contain varying amounts of conceptually identical values and use numbers (starting from 0) as the names of their properties.

RaYell's answer is good - it answers your question.
It seems to me though that you should really be creating an object keyed by labels with sub-objects as values:
var columns = {};
for (var i = 0; i < oFullResponse.results.length; i++) {
var key = oFullResponse.results[i].label;
columns[key] = {
sortable: true,
resizeable: true
};
}
// Now you can access column info like this.
columns['notes'].resizeable;
The above approach should be much faster and idiomatic than searching the entire object array for a key for each access.

How to Access Array of Objects in JavaScript ? - GeeksforGeeks
Using the brackets notation, you access objects in an array by specifying the array's name and the desired index. This method retrieves the entire object at the specified index. To access specific properties, combine it with dot notation for precision. ... Example: The code below demonstrates how we can use the brackets notation to access the elements of the array of objects.

Creating an array is as simple as this:
var cups = [];
You can create a populated array like this:
var cups = [
{
color:'Blue'
},
{
color:'Green'
}
];
You can add more items to the array like this:
cups.push({
color:"Red"
});
MDN array documentation

The array should be like this...
var cup = [];
After we putting properties to the array, it will be like this
[
{
"color": "blue",
"size": "large",
"type": "mug"
}
]
And you can put properties like this..
var cup = [];
cup.push({
color : 'blue',
size : 'large',
type : 'mug'
})
console.log(cup);Reddit

Hello! Just curious…do you guys like manipulating objects or arrays more? Pros and cons of both?
Personally I find dot notation with objects much much easier then iteration but I am a novice and I’m curious to know if my logic is flawed.
Thanks!

April 23, 2017 - What we do in the snippet above is use reduce, which returns accumulator (obj), to which we append each item in the array using that items id. This will convert our array of objects into an object of objects. YAY! (If reduce is confusing you please please please go check them out here!

An array is a special kind of object. The square brackets used to access a property arr[0] actually come from the object syntax. That’s essentially the same as obj[key], where arr is the object, while numbers are used as keys.
