In Javascript, use the push method of an array to add a new element with the

I am trying to populate a JavaScript array by using the push method to add individual elements.

I have successfully created the array like this:

Initializing the array:

var buildProduction = new Array();

Then, I define and add each element to the array using push:

var singleString = {step: 1, name: sName.value, description: sDescription.value, lon: sLon.value, lat: sLat.value, ficon: sIcon.value, img: filePathName}

buildProduction.push(singleString)

I repeat this process with different data, resulting in an array like this:

[
 {step: 1, name: sName.value, descri...},
 {step: 2, name: sName.value, descri...},
 {step: 3, name: sName.value, descri...},
 {step: 4, name: sName.value, descri...},
 {step: 5, name: sName.value, descri...},
 {step: 6, name: sName.value, descri...}
]

However, I would like to group these arrays under specific names, like this:

"ExampleName":[
  {step: 1, name: sName.value, descri...},
  {step: 2, name: sName.value, descri...},
  {step: 3, name: sName.value, descri...},
  {step: 4, name: sName.value, descri...},
  {step: 5, name: sName.value, descri...},
  {step: 6, name: sName.value, descri...}
]

Unfortunately, I am unsure of how to achieve this using push or any other method...

The solution is likely simple and may have been addressed elsewhere, but I am struggling to find the right search terms.

Answer №1

If your code is enclosed within an object called arrayObject, you can use the following method:

let arrayObject = {
ExampleName:[]
}

arrayObject.ExampleName.push(singleString);

This piece of code will insert strings into the ExampleName array belonging to arrayObject.

To gain a better understanding, refer to the standalone example below:

let step = 'step'

let arrayObject = {
    ExampleName: []
}
let singleString1 = { step1: 1 }
let singleString2 = { step2: 2 }
let singleString3 = { step3: 3 }

arrayObject.ExampleName.push(singleString1);
arrayObject.ExampleName.push(singleString2);
arrayObject.ExampleName.push(singleString3);

console.log(arrayObject);

Answer №2

It appears that you are looking to construct a JavaScript object and store an array inside of it. However, the array itself is not directly part of the object. To achieve this, simply define the object with the array property like so:

const myObject = {
"ArrayName": myArray
}
