Task
My task was to implement the rules of Conway's Game of Life as explained in rules.md. I
was given the choice of doing this in Java, JavaScript or Python, and chose JavaScript. I implemented the evolve() method in scripts/gol.js and added
tests to spec/golSpec.js to verify the correctness of my code.
The game grids are represented by two-dimensional arrays. Live cells are represented by 1s, and empty cells are represented by 0s. An example grid could look like this:
[
[0, 1, 0],
[0, 1, 1],
[0, 0, 0]
]The inner arrays in a grid passed to evolve() must be the same length.
Running Tests
The tests make sure that all the scenarios described in rules.md are satisfied.
Prerequisites
node.js - once installed, run npm install in this directory.
In node
npm test
Debugging
To run tests with a debugger, run the following then go to http://localhost:8282/debug?port=5858 in Chrome:
npm install -g jasmine-node-debug
jasmine-node-debug
Execution will initially be paused to allow you to add breakpoints.
In the browser
npm install -g webpack
npm run webpack-test
open _specRunner.html
Every time a change is made, run npm run webpack-test again and then refresh _specRunner.html in your browser window.
Debugging
As you would in the browser normally, except all your output will be concatenated into a single file bundle.js.
