How to code review?

• Review is a top-priority task. Review code soon as possible. It can help to avoid massive merge of PRs at the end of sprint and won’t waste time of team members, especially if tasks are related to each other.
• First of all you should check if the changes are related to the task. There shouldn’t be a thing like “let me also add this stuff to this PR by the way”.
• Initial PR comment should contain the link to corresponding trello card.
• You should not only check the code, but also check if the modified component is working correctly in the app. You check the code very carefully, every line. When checking the component in the app, you should test all possible use cases.
• The code should follow established code style and styled with prettier. Also, please follow English language rules and use common sense when naming variables. Do not repeat yourself, but keep it simple.
• Code review is not for critics, it’s rather a place for common effort to make a better product. That’s why it is

What it is	A JavaScript module exporting a single function.	An ESLint plugin.	An ESLint configuration.
What it does	Runs the code (string) through prettier then eslint --fix. The output is also a string.	Plugins usually contain implementations for additional rules that ESLint will check for. This plugin uses Prettier under the hood and will raise ESLint errors when your code differs from Prettier's expected output.	This config turns off formatting-related rules that might conflict with Prettier, allowing you to use Prettier with other ESLint configs like eslint-config-airbnb.
How to use it	Either calling the function in your code or via [prettier-eslint-cli](https://github.co

Basic Snake HTML and JavaScript Game

Snake is a fun game to make as it doesn't require a lot of code (less than 100 lines with all comments removed). This is a basic implementation of the snake game, but it's missing a few things intentionally and they're left as further exploration for the reader.

Further Exploration

• Score
• When the snake eats an apple, the score should increase by one. Use context.fillText() to display the score to the screen

Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages

// original gist
const shuffleArray = arr => arr.sort(() => Math.random() - 0.5);

// fully random by @BetonMAN
const shuffleArray = arr => arr
  .map(a => [Math.random(), a])
  .sort((a, b) => a[0] - b[0])
  .map(a => a[1]);

shuffleArray([1, 2, 3]) //[3, 1, 2]
