Check the Browser compatibility table carefully before using this in production.
The WebGL2RenderingContext.createQuery() method of the WebGL 2 API creates and initializes WebGLQuery objects, which provide ways to asynchronously query for information.
Syntax
WebGLQuery gl.createQuery();
Parameters
None.
Return value
A WebGLQuery object.
Examples
gl must be a WebGL2RenderingContext. WebGLQuery objects are not available in WebGL 1.
var query = gl.createQuery();
