What Vitsy sees

"Well, I'm a 1D language, so... for now, only the first line counts."

222 //X>"!dlroW ,olleH"Z
222                      push three twos
    //                   divide twice

What JavaScript ES6 sees

222 //X>"!dlroW ,olleH"Z

"Let's see... You put the number 222 and then put something in a comment. Alright, sure, I'll roll with that."

shush=0

"You made a variable. Noted."

alert("Hello, World!")

"Ah, I see where you're going with this. I'll display that."

sorry=`
listen
capture Hello, World!`

"Oo! A multiline string! Now we're talking, ES6 rulez, ES5 drools!"

(EOF)

"Well, I'm done. Peace out."

What Oration sees

222 //X>"!dlroW ,olleH"Z

"This wasn't on my notes...! Best not do anything."

shush=0
alert("Hello, World!")
sorry=`

"Oh, here's some extra notes."

listen

"Listen..."

capture Hello, World!`

"...Hello, World!"

(EOF)

"thinks Nothing more! Great, I'm done here. breathes deeply"

Minkolang explanation

(Too lazy to create narrative. Might do later, the code took a while.) Irrelevant code replaced with # or omitted. Also, added comments C ... C.
