I am doing this to clean the array theClouds = [];

function removeClouds(obj){
    var index = theClouds.indexOf(obj);
    if ( index > -1){
        theClouds.splice(index, 1);
        console.log(theClouds.length);
    }
}

function deleteClouds(){
    for (let u = 0; u < theClouds.length; u++){
        theCloud = theClouds[u];
        removeClouds(theCloud);
    }
}

But for some reason the loop stops in the middle, removes one or two and then ignore the rest, i have to click on the button that activates de function deleteClouds to force the loop and remove everything.

I forgot to mention, but theClouds[] is an array of arrays, I dont know if that concludes the same so theClouds = [ the.cloud = [x,y, image]]

Doing this will have the same point?
function deleteClouds(){
  theClouds = [];
    }
}
