i want to know basic details of esp8266;
i know arduino well, but i have nodemcu and i cant find some videos of it . most of people are using esp module without attached microcontroller with it !
horrible thing is i cant upload any blynk program on it and while selecting board as wemos, only some pins give response!
i also cant command it :(

i cant understand is there my low knowledge problem or nodemcu is not working properly?
i also hardly upgraded it, but dont know the upgrading process is really done or not because i cant use command
i have tried to command with arduino software

Usually nodemcu is used as a standAlone device because it reduces the need for a separate microcontroller.
Because it has its own processing unit.You can program it using either Lua or arduino libraries.
