The WebGLRenderingContext.createProgram() method of the WebGL API creates and initializes a WebGLProgram object.

None.

A WebGLProgram object that is a combination of two compiled WebGLShaders consisting of a vertex shader and a fragment shader (both written in GLSL). These are then linked into a usable program.

const program = gl.createProgram();

// Attach pre-existing shaders
gl.attachShader(program, vertexShader);
gl.attachShader(program, fragmentShader);

gl.linkProgram(program);

if (!gl.getProgramParameter(program, gl.LINK_STATUS)) {
  const info = gl.getProgramInfoLog(program);
  throw `Could not compile WebGL program. \n\n${info}`;
}

See WebGLShader for information on creating the vertexShader and fragmentShader in the above example.
