The WebGLRenderingContext.getShaderInfoLog returns the information log for the specified WebGLShader
object. It contains warnings, debugging and compile information.
Syntax
gl.getShaderInfoLog(shader);
Parameters
- shader
- A
WebGLShader
to query.
Return value
A DOMString
that contains diagnostic messages, warning messages, and other information about the last compile operation. When a WebGLShader
object is initially created, its information log will be a string of length 0.
Examples

/* load shader source code. */
gl.shaderSource(shader, shaderCode);
/* compile shader source code. */
