Panda / Javascript question :)

Hi @enpu / panda people

This is just a basic question about declaring variables and stuff. I'm just trying to learn to write more efficient code and use less space lol.

game.createScene('Stage04', {
    
    slot1: false,
    slot2: false,
    slot3: false,
    slot4: false,
    
    init: function() {

        if (this.slot1 === false) {
            // do something
        }

The code however works exactly the same, if I remove the variable declarations, like below ...

game.createScene('Stage04', {
    
    init: function() {

        if (this.slot1 === false) {
            // do something
        }

Is it better 'practice' to have the declarations there, or does it really serve no purpose in this case?

Thanks heaps for any feedback

Actually those two codes won't work exactly same.

if (this.slot1 === false) {
    // do something
}

If you don't define your variable, it's value will be "undefined", so that if statement will be false.

Personally i think it is more clear to define all the properties in the beginning of the class, especially in big classes. Look at the source code of Panda engine, every class has it's properties defined in the beginning of the class, and every single property and function is in alphabetical order, pretty clean code i would say

In other languages I try and define anything upfront for clarity and also its useful if I want to comment things sometimes, doing the same in my baby steps in JS and Panda as well.
