The potential and options of functions organized and defined within an Array

The potential and options of functions organized and defined within an Array

I'm currently facing difficulties in organizing my code efficiently.

Let me illustrate the structure I have in mind:

var Test = {
  old: [
    get: function(who, when){
       returrn({ subject: "Old test 001", text: "The test 001 was perform by "+who });
    },
    get: function(who, when){
      returrn({ subject: "Old test 002", text: "The "+when+" the test 002 was performed"});
    }
  ],
  new: [
     //Same thing
  ]
};

The issue arises when trying to implement this structure as it seems not feasible. I am seeking advice on how to declare functions within an array. This is necessary because each method 'get()' of the array should return a different message and may include variables passed in parameters positioned differently within the text, thus requiring explicit declaration.

I've considered the following alternative approach:

var Test = {
  old: [
    one: {
      get: function(who, when){
        returrn({ subject: "Old test 001", text: "The test 001 was perform by "+who });
      },
    },
    two: {
      get: function(who, when){
        returrn({ subject: "Old test 002", text: "The "+when+" the test 002 was performed"});
      }
    }
  ],
  new: [
     //Same thing
  ]
};

This option does not meet my requirements as I need to access the content dynamically, like

Test.old[test_id].get("toto", "02/04/2013")

. Unfortunately, indexing items by numerical values in JSON is not allowed.

If there's no better solution, I will proceed with this setup.

In this context, what would be the most suitable approach?

Thank you!

Answer №1

Although the question is a bit unclear, it's evident why your code isn't functioning properly. The issue lies in mixing up arrays and objects. Here's how array literals are structured:

var myArray = [
  "first item",
  "second item",
  {value: "third item"},
  ["first/only item in fourth item"],
  1,
  2,
  3.14159,
  function(a,b) { return a + b; },
  "etc."
];

You interact with array items using push, pop, shift, unshift, and numerical indexes.

On the other hand, object literals appear like this:

var myObject = {
  one: "some value",
  two: {
    value: "object values can be anything"
  },
  123: 456,
  "a million": function (a, b) { return a - b; }
};

Access to object items requires string indexes.

Lastly, make sure you have a returrn() function defined somewhere. Otherwise, why not just return your return values directly?
