Implement the game Connect Four such that the source code of game.js is as short as possible without editing any other files.
Gameplay is as described here:
- Game board is 6 x 7 (6 rows and 7 columns)
- Players alternate turns
- Player 1 is yellow; Player 2 is red
- The object of the game is to connect 4 same colored discs in a row (down, across, or diagonally)
- Play continues until a player wins
- Clicking on the game board will cause the disc to be "dropped" into that column
- Attempting to place a disc in a column that is full is ignored
- Upon winning, the string 'WINNER!' must be logged to the console and no further moves can be made
- No errors are thrown through normal gameplay
- Must pass all tests
- Must conform to the ECMAScript 5 specification
- No external libraries
For development, please install Yarn and run yarn install.
There are several commands (see package.json) which are useful in development:
| Command | Description |
|---|---|
yarn test |
Runs tests |
yarn char-count |
Returns the number of characters in static/game.js |
yarn char-count-min |
Minifies code and returns the number of characters in the minified version |
yarn compare-counts |
Compares character count between versions of static/game.js |
yarn minify |
Minifies static/game.js |
yarn beautify |
Beautifies static/game.js (makes it more readable) |
yarn start |
Builds and runs server |
yarn debug |
Builds beautified version of JS for debugging and runs server |
yarn watch |
Runs a dev build whenever the file is changed |
The test suite consists entirely of integration tests so as not to constrain the implementation in any way. For testing, a simple static file server is stood up and then UI tests are run against the code (see test.js).
Run tests via yarn test.
yarn start will run a server on port 3000 by default and yarn test will use port 3001. To specify a different port, use the PORT environment variable like so:
PORT=3333 yarn test
