package-scripts.yml, line 33 at r1 (raw file):

      default:
        description: Run prettier-eslint on JS.
        #script: prettier "packages/**/*.@(js|jsx)" "spec/dummy/client/app/**/*.@(js|jsx)" "webpack.config.babel.js" "webpack/**/*.js" --write

space after # sign. Also why comment out these scripts instead of just removing them?

node_package/src/buildConsoleReplay.js, line 17 at r1 (raw file):

      let val;
      try {
        val = (typeof arg === 'string' || arg instanceof String) ? arg : JSON.stringify(arg);

Parentheses make this statement more readable, I believe

node_package/src/context.js, line 9 at r1 (raw file):

export default function context() {
  return ((typeof window !== 'undefined') && window) ||
    ((typeof global !== 'undefined') && global) ||

keep parentheses for readability?
