jscrunch by hand

jscrunch_by_hand.js

// HAND MADE JSCRUNCH

ORIGINAL_CODE = '-que tal está isso asd? quero que fiques comigo querida asd.'


// naive approach

// 1) replace 'que' with ''
_ = '- tal está isso asd? ro  fis comigo rida asd.'
_.split('').join('que')

// 2) replace 'asd' with ''
_ = '- tal está isso ? ro  fis comigo rida .'
_
  .split('').join('que')
  .split('').join('asd')


// Now let's apply the jscrunch algorithm:
// For every character in $ it is splitting _ on the character,
// using with to make the resulting array the scope.
// Then joining the pieces using the last piece and reassigning to _


// 3 lets apply it, replacing each word at a time...

// 3a)
_='-que tal está isso asd? quero que fiques comigo querida asd.'

// 3b)
_='- tal está isso asd? ro  fis comigo rida asd.que'
for (Y in $='') with (_.split($[Y]))
  _ = join(pop())

// 3c)
_='- tal está isso ? ro  fis comigo rida .queasd'
for (Y in $='') with (_.split($[Y]))
  _ = join(pop())


// then eval the expanded _ var :D
