The read-only WebGLActiveInfo.type property represents the type of the requested data returned by calling the getActiveAttrib() or getActiveUniform() methods.
The WebGLRenderbuffer interface is part of the WebGL API and represents a buffer that can contain an image, or can be source or target of an rendering operation.
The WebGLVertexArrayObject interface is part of the WebGL 2 API, represents vertex array objects (VAOs) pointing to vertex array data, and provides names for different sets of vertex data.
The XMLHttpRequest.response property returns the response's body. It can be of the type ArrayBuffer, Blob, Document, JavaScript object, or a DOMString, depending of the value of XMLHttpRequest.responseType property. Value of response is null if the request is not complete or was not successful. However, if the value of responseType was set to "text" or the empty string, response can contain the partial text response while the request is still in the loading state.
The XMLHttpRequest.responseType property is an enumerated value that returns the type of the response. It also lets the author change the response type to one "arraybuffer", "blob", "document", "json", or "text". If an empty string is set as the value of responseType, it is assumed as type "text".
The XMLHttpRequest.responseURL property returns the serialized URL of the response or the empty string if the URL is null. If the URL is returned, URL fragment if present in the URL will be stripped away. The value of responseURL will be the final URL obtained after any redirects.
The XMLHttpRequest.responseXML property returns a Document containing the response to the request, or null if the request was unsuccessful, has not yet been sent, or cannot be parsed as XML or HTML. The response is parsed as if it were a text/xml stream. When the responseType is set to "document" and the request has been made asynchronously, the response is parsed as a text/html stream. responseXML is null for data: URLs.
The XMLHttpRequest.status property returns the numerical status code of the response of the XMLHttpRequest. status will be an unsigned short. Before the request is complete, the value of status will be 0. It is worth noting that browsers report a status of 0 in case of XMLHttpRequest errors too.
