Code Style

Project configured to use following rule chain:

.editorconfig -> .prettierrc -> .eslint

• .editorconfig will tell your editor how to handle spaces and newlines
• .prettierrc will add some newlines, spaces and brackets to make code easier to read
• .eslintrc will strict code to the rules, to exclude oblivious errors

Recommended VSCode settings plugin:

  "editor.tabSize": 2,
  "editor.formatOnSave": true,
  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": true,
  },
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "[javascript]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode"
  },
