<canvas id="canvas"></canvas>

JavaScript

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

Playable code
<canvas id="canvas" width="400" height="200" class="playable-canvas"></canvas>
<div class="playable-buttons">

  <input id="reset" type="button" value="Reset" />
</div>
<textarea id="code" class="playable-code">
ctx.translate(50, 50);
ctx.fillRect(0,0,100,100);
ctx.setTransform(1, 0, 0, 1, 0, 0);</textarea>

var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
var textarea = document.getElementById("code");
var reset = document.getElementById("reset");
var edit = document.getElementById("edit");
var code = textarea.value;
function drawCanvas() {
  ctx.clearRect(0, 0, canvas.width, canvas.height);
  eval(textarea.value);
}
reset.addEventListener("click", function() {
  textarea.value = code;
  drawCanvas();
});
