Generate an array containing multiple arrays with variable names

Question

I am working on creating an array for each user and storing them in another array. Here is the code snippet I used for this:

var arrays = [];
var userCounter = 1;
@foreach($eventUsers as $user)
{
   arrays['arr' + userCounter] = [];
   userCounter++;
}

When I console.log(arrays), it showed me the following output:

[arr1: Array[0], arr2: Array[0], arr3: Array[0], arr4: Array[0]]

Now, I need to add elements to each individual array (arr1, arr2, arr3, arr4) while looping through 'arrays'.

I attempted the following approach:

for (arrayName in arrays) {
    arrayName.push('x');
}

Unfortunately, this didn't work as expected. Can anyone provide a solution?

Answer №1

Construct your array

let customArrays = {}, index;
for (index = 0; index < 5; index++) {
    customArrays['customArray' + index] = [];
}

Modify the customArrays

// loop through the keys
for (index in customArrays) {
    // update the values
    customArrays[index].push('updatedValue');
};

What you need is a specific object:

var myObject = {};
myObject.name = "John";
myObject["age"] = 30;
console.log(myObject);

Refer to this article for guidance on how to iterate through an object, and visit this page for additional information.
