Exploring the array pushing functionality in MongoDB

Question

Exploring the array pushing functionality in MongoDB

I have received a MongoDB query outputting two fields (110, 1; 105, 1; 105, 2). My goal is to store these results in an array for use in a while loop:

110, 1
105, 1
105, 2

I have attempted to create a function for this task, but my array remains empty:

  'otherHelperFunction': function(){
  var array = {};
  var finalSpielertemp = UserSpieler.find({UserID: 1}).map(function(doc) {
    {$push: array{doc.SpielerID, doc.SpieltagID}};
  });
}

How should I define the array correctly? It seems like using var array = {} is not the right approach. Additionally, what is the correct method for pushing elements into the array?

I would appreciate any guidance or tips on how to solve this issue. Thank you.

Answer №1

Regrettably, the code you've provided along with your explanation is quite confusing. It's difficult for me to comprehend what you're attempting to achieve, therefore I'm unable to offer assistance.

It appears that there may be some confusion between the concepts of objects and arrays. Let me provide a simple clarification on the difference. I highly recommend delving into the fundamentals of JavaScript by enrolling in an online course such as this one!

To clarify:

An array is declared like so:

var array = [];

Whereas, an object is declared as follows:

var object = {};

In terms of storing data:

Arrays handle data in this manner:

[ 1, 2, 3, 4, 5 ]

Conversely, objects manage data like this:

{ name: "Ben", age: 25, country: "France" }
