Create array of arrays with dynamic names

Question

I want to create array for each user and store them in another array. For that I used this code:

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

and console.log(arrs); gave me the output

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

Then I need to push elements to each array(arr1, arr2, arr3, arr4) while looping through 'arrs'

I tried using:

for (arr in arrs) {
    arr.push('x');
}

But didn't work. Can anyone give me a solution?

What language is this? In any case, instead of using keys `arr1` etc., just use array indexes. — , Jun 08 '15 at 09:43

Build your array

var arrs = {}, i;
for (i = 1; i <= 4; i++) {
    arrs['arr' + i] = [];
}

update the arrs

// iterate over the keys
for (i in arrs) {
    // make your assignment
    arrs[i].push('x');
};

What you want is an object:

var obj = {};
obj.test = "a string";
obj["test2"] = "another string";
console.log(obj);

Check this post for how to loop though an object, and this post for more info.
