Installation & Update
$ npm install -g planetproto@latest
Some npm installations require use of
sudo in the above command. Recommend to instead reinstall node/npm so you don't need sudo.
1. Selecting a problem to work on
Once the workshop is installed, run
planetproto to print a menu
where you can select a problem to work on.
Problems are listed in rough order of difficulty. You are advised to complete them in order, as later problems will build on skills developed by solving previous problems.
2. Writing your solution
Once you have selected a problem, the workshop will remember which problem you are working on. Using your preferred editor, simply create a file to write your solution in. Most problems will supply some boilerplate with which to get started.
Many challenges will ask you to make a 'claim'. We have provided
claim as a global function.
To make a claim write
claim(actual, expected), e.g.:
claim(1 === 1, true);
3. Verifying your solution
Your solution will be verified against the output of the 'official' solution. If all of the output matches, then you have successfully solved the problem!
$ planetproto verify mysolution.js
Feedback and criticism is welcome, please log your troubles in issues.
node planetproto.js to run the workshop
node planetproto.js verify 010.js to verify a submission
