deleteShader

Hi,

Is this forum alive?

I am reading the first chapters of the book, and noticed the
gl.deleteShader call has been used on listing 2-1 but not on
2-2. So far can't tell if the book will eventually shed light on this.
Any hints?

Listing 2-1:

Code:

  if (!gl.getShaderParameter(shader, gl.COMPILE_STATUS)) {
      alert("Error compiling shader" + gl.getShaderInfoLog(shader));
      gl.deleteShader(shader);   
      return null;
  }

Listing 2-2:

Code:

  if (!gl.getShaderParameter(shader, gl.COMPILE_STATUS)) {
    alert(gl.getShaderInfoLog(shader));
    return null;
  }

Thanks,
Everton
