Preferred Prettier configuration for JavaScript/ECMAScript

For JavaScript based apps, 

• The code must be formatted with the Prettier engine with the following configuration
• prettierrc file (YAML)
• arrowParens: avoid
• bracketSpacing: true
• insertPragma: false
• jsxBracketSameLine: false
• printWidth: 120
• proseWrap: preserve
• requirePragma: 'false'
• semi: false
• singleQuote: true
• tabWidth: 2
• trailingComma: none
• useTabs: false
• The code must be linted with the standardjs linter: https://standardjs.com/
• Recommend using prettier-eslint plus the appropriate plugins to get both standard and eslint processing done at the same time. Here is the configuration we use for prettier-eslint: .eslintrc.yml.
• This will give you both prettier and standard configuration that adheres to the above.
• Prefer simple functional style over class heavy designs
