Renaming variables to respected translated languages

[robertoooc]

Is your feature request related to a problem? Please describe.

I was looking at the documentation in various languages, then noticed the constant use of English variable names as opposed to their translated names. This happens especially within callback functions where the parameters are consistently named "response" or "error".

Describe the solution you'd like

It would greatly benefit non-English speakers who are learning or referencing the documentation if these variables were translated to their respective languages.

Describe alternatives you've considered

Just renaming some variables.
Spanish example: .then(function (response)) ---> .then (function (respuesta))
