ExperimentalWebGL

ExperimentalWebGL is a non-standard rendering context name used by some web browsers to expose the WebGL API before the interface was stabilized as a formal standard. It was requested by calling canvas.getContext('experimental-webgl'), providing an OpenGL ES 2.0–style JavaScript API for rendering 3D graphics inside a web page.

As the WebGL specification matured, browsers standardized on the 'webgl' context. The experimental variant served mainly as a transitional or testing path for early adopters and for vendor experimentation. In modern browsers the experimental-webgl context is largely obsolete and may be unsupported or ignored, depending on the browser version.

Compatibility is uneven: some very old browser builds implemented experimental-webgl, while newer releases often remove it. Developers targeting current environments should prefer 'webgl' and provide fallbacks to 'webgl2' or to 2D rendering where WebGL is unavailable.

Security and stability considerations discourage new projects from using experimental-webgl because it is non-standard and not guaranteed to remain available. Relying on it can lead to portability problems or breakages when browsers update.
