Understanding JavaScript Prototypes - Workshop
The goal of this workshop is to help you understand the object model in Javascript by learning how prototypes work.
Most guides / tutorials start explaining JavaScript objects by going directly to ‘constructor functions’, this workshop is different, it starts simple by explaining prototype chains and building from there.
Please read the exercises thoroughly and obey all conditions, they are there to help you learn!
$ 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.
Once the workshop is installed, run planetproto
to print a menu
where you can select a problem to work on.
$ planetproto
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.
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);
Use the workshop's run
command to point the workshop at your solution file. Your solution will loaded
and passed the problem input. This usually won't perform any validation, it will only show the program output.
$ planetproto run mysolution.js
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.
