core-vanilla-javascript's Issues

First test for Sudoku seems to be incorrect

After splitting the string "..9.7...5..21..9..1...28....7...5..1..851.....5....3.......3..68........21.....87" into 9 arrays, we get this board. There are no duplicate values in neither the columns nor rows.

  [ '.', '.', '9', '.', '7', '.', '.', '.', '5' ],
  [ '.', '.', '2', '1', '.', '.', '9', '.', '.' ],
  [ '1', '.', '.', '.', '2', '8', '.', '.', '.' ],
  [ '.', '7', '.', '.', '.', '5', '.', '.', '1' ],
  [ '.', '.', '8', '5', '1', '.', '.', '.', '.' ],
  [ '.', '5', '.', '.', '.', '.', '3', '.', '.' ],
  [ '.', '.', '.', '.', '.', '3', '.', '.', '6' ],
  [ '8', '.', '.', '.', '.', '.', '.', '.', '.' ],
  [ '2', '1', '.', '.', '.', '.', '.', '8', '7' ] 

Day 1 objectives are not achieved by Day 1 plan

In solo_study.md, the Day 1 plan is to complete the Treehouse JavaScript Basics course. However, several of the Day 1 objectives are not covered in that course. (It's possible they're covered in the Stretch section -- I haven't completed those, so I'm not sure.) I'm also not sure why understanding arity is an objective. MDN indicates it's obsolete (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/arity).

Here's the Day 1 objectives list, with a note indicating whether each objective is covered in the course:

• Basic understanding of variables (YES)
• Basic string and array manipulation (strings -- YES; arrays -- NO)
• Understand 'truthy' and 'falsey' (NO)
• Understand literal notation (NO)
• Understand dot bracket notation (NO)
• Basic understanding of JSON (NO)
• Understand Operator precedence (NO)
• Practice Flow control: iteration, if, switch, while, for loops (if -- YES; all others -- NO)
• Understand and practice Functions: arguments, arity, return, scope (arguments, return, scope -- YES; arity -- NO)
