Answer

out of the window =  standard English
This would be correct in any context

out the window      = informal/regional English
Many English speakers say this, but I wouldn't recommend you copy them. Not everyone would see this as acceptable.

outta the window   = extremely informal.
You should not use this style of writing.  Note that  "outta" - like "gonna" - is not an actual word in standard English, but the written transcription of the sounds made in relaxed speech.

Answer

표현이 똑 같아요. 근데 'outta' 속어 같은 느낌이 들어요.
