Canvas doesn't draw in a loop

Why draw arent rectangles in a loop? I just started a snake game n trying to draw the snake's body through a loop, but for some reason ctx is not drawing the loop. If I write the rectangle without the loop, it works.

var canv = document.getElementById('canv');
var ctx = canv.getContext("2d");

var snake = [];
snake[0] = {x:100, 100};
snake[1] = {x:90, 100};
snake[2] = {x:80, 100};

var i;

function draw() {
   for (i = 0; i > snake.length; i++) {
     ctx.fillStyle = "yellow";
     ctx.rect(snake[i].x, snake[i].y, 22, 300); 
     ctx.fill();
 }

setInterval(draw,100);
