如何运行从 C 编译的 JS 脚本

Question

I need to understand how to run compiled JS script CORRECTLY because I got some erorrs.

What I have:

#include <stdio.h>
#include <string.h>

void printNewLines(int amountOfNewLines);

int main() {
   char answerFromUser;

   printf("Hello man, I need you to enter single character. ");
   scanf("%c", &answerFromUser);
   printNewLines(3);
   printf("OMG, you entered: %c", answerFromUser);

   scanf(" %c", &answerFromUser); //To prevent immediate exit
   return 0;
}

void printNewLines(int amountOfNewLines)
{
   for (int newLine = 0; newLine < amountOfNewLines; newLine++)
   {
      printf("\n");
   }
}

When I compile it to JS and run using Emscripten on WSL, I get this:

And when I compile it with -o file.html option and try to paste script from JS file to Firefox console I get this:

It seems even scanf() doesn't work. So, what am I doing wrong and how to compile files properly?

Well, first of all I need to run HTTP server using node or something else. Then override window.prompt method to handle inputs from user.
