ESLint Reset - A starter .eslintrc file that resets all rules to off and includes a description of what each rule does. From here, enable the rules that you care about by changing the 0 to a 1 or 2. 1 means warning (will not affect exit code) and 2 means error (will affect exit code).
{
// http://eslint.org/docs/rules/
"ecmaFeatures": {
"binaryLiterals": false, // enable binary literals

"defaultParams": false, // enable default function parameters
"forOf": false, // enable for-of loops
"generators": false, // enable generators
