How are you? I'm practicing some JavaScript, since I'm new to it, and I'm trying to create a "space invaders" game with p5.js. I have made some progress, but, I have encountered a problem that I can not solve:

var ship;
var aliens = []; 
var missiles = [];
...
...
function keyPressed() {
if (key === ' ') {
    var missiles = new missile (width/2, height/2);
    missiles.push(missile)

When I try to test by pressing the space bar, it tells me the following:

It is assumed that when you press the spacebar, the code adds a new element to the missiles array, but why does it throw that error?

With this, your problem should be solved, taking into account that you only want to add those parameters to the previously defined array:

var ship;
var aliens = []; 
var missiles2 = [];
...
...
function keyPressed() {
if (key === ' ') {

  //creamos el objeto que deseas con sus parametros
   var obj = new missile (width/2, height/2);
  //agregamos el objeto al array
   missiles2.push('obj');

}
