Description
In this assignment, you will be required to write JavaScript functions that simplify playing of the
variation of Connect Four.
1.1 Data File Specification
An example of properly formatted file is shown in Figure 1. The first file encodes a game and the
second file encodes the moves to be made.

2 One Player, One Move
The first part (onePlayerOneMove in the file csce322assignment02part01.js) will take in one
(1) argument (a game) and return a function that takes in one (1) argument (a move), and returns
the game that is the result of Player 1 dropping a 1 into the column of the game denoted by the
move. The 1 should fall (move down through the -’s in the column) until it reaches a space that
is not – or reaches the last row in the game. An example is provided below

3 One Player, Many Moves
The second part (onePlayerManyMoves in the file csce322assignment02part02.js) will take in
one (1) argument (a game) and return a function that takes in one (1) argument (an arry of moves),
and returns the game that is the result of Player 1 playing each move in succession (following the
rules of onePlayerOneMove) until all of the moves in the array have been played, or Player 1 has
placed four (4) 1’s in a row horizontally, vertically, or diagonally.

4 Many Players , One Move
The third part (manyPlayersOneMove in the file csce322assignment02part03.js) will take in one
(1) argument (a game) and return a function that takes in one (1) argument (an arry of moves), and
returns the game that is the result of each player in the game making exactly one move until each
player has completed a move or a player has won the game (placed four of their pieces vertically,
horizontally, or diagonally). Player 1 places 1s, Player 2 places 2s, etc. (you may assume the
highest number in the provided game is the number of players in the game). The moves are made
in the order they appear in the moves array.

5 Many Players , Many Moves
The fourth part (manyPlayersManyMoves in the file csce322assignment02part04.js) will take
in one (1) argument (a game) and return a function that takes in one (1) argument (an arry of
moves), and returns the game that is the result of each player in the game taking turns making a
move until all of the moves in the array have been exhausted or a player has won the game (placed
four of their pieces vertically, horizontally, or diagonally). Player 1 places 1s, Player 2 places 2s,
etc. (you may assume the highest number in the provided game is the number of players in the
game).

6 Extra Credit (10%)
Games will contain an arbitrary number of players.
7 Naming Conventions
Your files should follow the naming convention of
csce322assignment02part01.js, csce322assignment02part02.js, csce322assignment02part03.js,
and csce322assignment02part04.js.
7.1 helpers.js
A file named helpers.js has been provided with the functionality to read the .cnf files into
matrices. If a modified helpers.js file is not included with your submission, the default will be
used in its place.
8 webgrader Note
Submissions will be tested with node.js, not the browser. cse.unl.edu is currently running
version 8.11.4 of node.
