Fibonacci Triangle Golfed

  1. // by Arnauld - https://codegolf.stackexchange.com/users/58563/arnauld
  2. f=(n,a=b=1,p)=>n?''.padEnd(p)+a+`+${b}=${b+=a}
  3. `+f(n-1,b-a,(a+"").length-~p):''
  4.  
  5. console.log(f(20))

Great golfed solution to this question at codegolf stackexchange by user Arnauld

A friend of mine had this idea the other night so I coded it up…

Update: I forgot to mention, this uses this list of words from google…

JavaScript Exotic Undefined

  1. // from Martin Kleppe
  2. Array: [][[]]
  3. String: ""[""]
  4. Function: ($=>$)()
  5. Object: ({}).$
  6. Number: 0.0.$
  7. RegExp: /$/.$
  8. Boolean: false.true

Fun tweet from Martin Kleppe today

// javascript // undefined

osx Command Files

  1. #!/bin/bash
  2. cd "$(dirname "$0")"
  3. . ~/.nvm/nvm.sh
  4.  
  5. nvm use stable && npm run dev

Then name that file “whatever.command”. When you double-click it, it’ll launch a terminal and run the command. I pop these in my dock for projects I’m always opening…

Label Thoughts

  1. main:{
  2.   header:{
  3.     {'Tasker'}
  4.     newCol:{'New Column'}
  5.   }
  6.  
  7.   columns:{
  8.     scroll:{
  9.       NoteCols:{}
  10.     }
  11.   }
  12. }
  13.  
  14. NoteCol:{
  15.   title:{['editable', 'focus']
  16.     close:{
  17.       {'&times;'}
  18.     }
  19.   }
  20.   newNote:{['editable', 'placeholder="New Note..."']}
  21.   hr:{}
  22.   noteContainer:{
  23.     Notes:{}
  24.   }
  25. }
  26.  
  27. Note:{['focus']
  28.   close:{
  29.     {'&times;'}
  30.   }
  31.   checkbox:{}
  32.   content:{['edtiable']}
  33. }
  34.  
  35. console.log('no errors :D');

The above is actually valid javascript, just a bunch of labels, blocks and a few arrays
