3. Clone your newly created repo: https://github.com/<%your_github_username%>/core-js-oop/

4. Go to folder core-js-oop

5. To install all dependencies use npm install

6. Each task is usually one or more classes:

   /**
    * Must correctly extend Employee.
    */
   export class Developer {
     /**
      * @param {string} name - Developer name.
      * @param {number} salary - Base salary.
      * @param {number} bonus - Bonus amount.
      */

     }
   }

   Read the task description in the comment above the class/method. Try to understand the idea. You can see the tests prepared if you don't understand it.

   Uncomment the incoming parameters:

    constructor(/* name, salary, bonus */) {...}

   Remove the throwing error line from function body:

   throwNotImplementedError();

   Implement the class/method by any way and verify your solution by running tests until the failed test become passed (green).

FAQ

Question: I use Windows machine and have received a lot of errors like "Expected linebreaks to be 'LF' but found 'CRLF'". How to handle it? Answer:

• First, you need to install Gitbash properly: you need to choose option "Checkout as-is, commit as-is" in section "Configuring the line ending conversions". It'll let you download repos with line endings set "as-is" as well as commit. In other words, not to change them at all, because by default it converts them.
• Second, install editorconfig plugin to your editor. For VS Code you can find it here: https://marketplace.visualstudio.com/items?itemName=EditorConfig.EditorConfig I'll let you apply some rules when you saving your files in the repo. This plugin will use config-file .editorconfig that you can see in the root folder. It lets you save the file with needed line endings, trim whitespaces, etc.
• Finally, you need to apply linter's autofix feature in order to fix all linebreaks that was already changed to "CLRF":

  npm run lint:fix

Question: The solution in the local repository succeeds and all tests are "green", but in the application some tests don't count. What to do?
Answer: Update your repository fork, update the local repository from the fork, run tests and fix your solution. After fixing, resubmit your solution for testing.

Question: How can I run tests for one task, and not all at once?
Answer:

npx mocha test/<task-name>.test.js
