Trippy array Loop Project

For my array loop project, I used some of my old code with the new array loop functions to make a better version of one of my past projects.

The code:var blocations = [];

var speeds = [];

var rectX

function setup() {

// put setup code here

createCanvas(1260, 600);

blocations[0] = 1;

blocations[1] =100;

blocations[2] =500;

blocations[3] = 50;

speeds[0] = 5;

speeds[1] =3;

speeds[2] =-6

speeds[3] =4

}

function draw() {

// put drawing code here

background('white');

fill('red');

rect(100,mouseY, 80, 80);

fill('magenta');

rect(100,mouseY, 60, 40);

fill('blue');

rect(mouseX,100,80, 80);

fill('cyan');

rect(mouseX,100,60, 35);

fill('green')

rect(500,mouseY,80,80);

fill('pink')

rect(500,mouseY,40,70);

fill('yellow')

rect(mouseX,500,80,80);

fill('silver')

rect(mouseX,500,10,65);

fill('cyan')

rect(mouseX,mouseY,50,50);

fill('pink')

rect(mouseX,mouseY,20,80);

fill('lime')

rect(mouseX,mouseY,70,10);

for(var i=0; i <10; i++){

for(var j=0; j <6; j++)

{

fill('white');

rect(i * 100, j* 100+50, 50, 50);

fill('white')

rect(i * 100+50, j* 100, 50, 50);

}

}

fill('gold');

rect(blocations[0], blocations[1], 35, 35);

rect(blocations[2], blocations[3], 35, 35);

for (var i = 0; i<blocations.length; i++){

blocations[i] = blocations[i] + speeds[i];

}

function keyPressed(){

if (keyCode === LEFT_ARROW){

//this will move my platform left

///console.log('left');

rectX -= 50;

}

else if(keyCode === RIGHT_ARROW){

//this will move my platform right

//console.log('right');

rectX += 50;

}

}

}
