method of the WebGL API returns information about the buffer.
js
getBufferParameter(target, pname)
target
A GLenum
specifying the target buffer object. Possible values:
gl.ARRAY_BUFFER
Buffer containing vertex attributes, such as vertex coordinates, texture coordinate data, or vertex color data.

gl.COPY_READ_BUFFER
Buffer for copying from one buffer object to another.
gl.COPY_WRITE_BUFFER
Buffer for copying from one buffer object to another.
gl.TRANSFORM_FEEDBACK_BUFFER
Buffer for transform feedback operations.
gl.UNIFORM_BUFFER
Buffer used for storing uniform blocks.
gl.PIXEL_PACK_BUFFER
Buffer used for pixel transfer operations.
gl.PIXEL_UNPACK_BUFFER
Buffer used for pixel transfer operations.
pname
A GLenum
specifying information to query. Possible values:
gl.BUFFER_SIZE
Returns a GLint
indicating the size of the buffer in bytes.
gl.BUFFER_USAGE
Returns a GLenum
indicating the usage pattern of the buffer. One of the following:
gl.STATIC_DRAW
gl.DYNAMIC_DRAW
gl.STREAM_DRAW

gl.STATIC_READ
gl.DYNAMIC_READ
gl.STREAM_READ
gl.STATIC_COPY
gl.DYNAMIC_COPY
gl.STREAM_COPY
js
