regarding for this subject page
I see two companies (amazon by firfox and google by chrome) are used emscripten technology to run c/c++ code on web by converted to javascripe
there are different SDK for both, Native Client SDK by chrome and emscripten sdk by firefox
I need to know which is fast SDK ( Amazon emscripten sdk or Google Native Client sdk)?
and why Unreal engine 4 wasn’t used Native Client-sdk as on chrome native client sdk?
if I need to used custom unreal build tool (UBT) files for architecture study, where I can start and how I can got that files to used on own separate project.
