Canvas tryouts

first try
second try (using loops to create a spectrum of colours)
third try I got stuck with this one. The goal was to create a shape by rotating a single line using if statements. No rotate functions.

 function init(){
       var canvas = document.getElementById('canvas1');
       var ctx = canvas.getContext('2d');
       var width = canvas.width;
       var height = canvas.height;
       var y = 200;
       var x = 10;

var rectSize = 10;

for(var h=0;h<80;h++) { var xPos=x*i;

       for(var i=0;i<80;i++) {

var yPos =(x+1)*i;

for (var j=0;j<80;j++){

           ctx.fillStyle = 'rgb('+4*h+','+4*i+','+4*j+')'

ctx.fillRect((x+1)*j,yPos,rectSize,rectSize); } }

       }
   
 }

</canvas>
