V8JS JavaScript v8dmoj 8.1.307.31

This is a custom version of V8 that adds six functions in order to perform I/O and aid in online judging.

  • print(...): similar to Python's print, prints all argument separated by space followed by new line.
  • flush(): flushes stdout, ensuring everything output by print()immediately shows up.
  • gets(): similar to the Ruby equivalent, returns one line of input from stdin.
  • read(bytes): read bytes bytes from stdin as an ArrayBuffer.
  • write(buffer): write a typed array, ArrayBuffer, or a view of ArrayBuffer to stdout.
  • quit(code): exits the program with code.

You can also assign to the global variable autoflush to control whether print() flushes.
