 Those strings, for example `['/assets/i18n/core/', '/assets/i18n/vendors/']`,   
 will load your translations files for the lang "en" from : `/assets/i18n/core/en.json` and `/assets/i18n/vendors/en.json`

-**For now this loader only support the `json` format.**

-Instead of an array of `string[]`,  
-you may pass a list of parameters:
-- `prefix: string = '/assets/i18n/'`
-- `suffix: string = '.json'`

-export function HttpLoaderFactory(_httpBackend: HttpBackend) {

-        {prefix: './assets/i18n/vendors/'}, // , "suffix: '.json'" being the default value

 The loader will merge all translation files from the server using [deepmerge](https://github.com/KyleAMathews/deepmerge).
