Javascript delete method

Question

I am trying to create a canvas game using the proccessing.js library.

I use an array to hold all my objects.

class blah{
    ...
    void delete(){
       // this.remove ???
    }
}

blah myArray = [];
myArray.push(new blah());

Is there a way I can create a delete function inside that class so that when the element is deleted it is removed from the array? I have thought of a workaround like passing as an argument the element's position in the array. Isn't there a direct way to delete it without passing any argument?

The workaround I told above:

void delete(int i){
  myArray.splice(i,1);
}

I'm confused: JavaScript doesn't currently support classes or static typing... Am I missing something? — Xophmeister

Your code snippet is confusing. In JavaScript you don't declare type of variable and you don't type the return value. Are you sure this isn't ActionScript or Java ? — HoLyVieR

I am using processing.js as I mentioned in the tags and at the begging of my question. This library allows C++-like declarations. processingjs.org/learning — XCS

@Xophmeister just another library which ruins the basic idea of JavaScript. Flexibility, create your own 'stuff'... — benqus

@benqus Not really. This is a great library, and I am not a big fan of libraries. But as C++ was the first language I have learnt this really helps in reducing the code size. You can create a fully-functional canvas game in 100 lines, which would take like 300 in pure javascript. And the good part is that I don't have to learn any new library because with this one you can still write in pure javascript, but you can still use the advantages of more advanced OOP languages like C++. — XCS

You should be able to find the instance with indexOf:

void delete() {
    int index = myArray.indexOf(this);

    if (index > -1) {
        myArray.splice(index, 1);
    }
}
