Issue 3692 - Created global eslintrc

eslintrc.json

 {
   "extends": "eslint:recommended",

     /* MDN General practices */

According to the documentation, it seems vars-on-top isn't included in
eslint:recommended. So might overriding this option be redundant?

+
     /* MDN Naming and formatting code */
     "no-trailing-spaces": "error",
     "max-len": ["error", 80],
     "brace-style": ["error", "allman"],

     /* MDN JavaScript practices */

I just noticed, instead of completely disabling no-unused-vars, we could rather
configure it to ignore global variables and function arguments, so that it still
catches unused local variables, which I think have no legit use whatsoever:

  "no-unused-vars": ["error", {"vars": "local", "args": "none"}]

     "array-bracket-spacing": "error",
     "arrow-spacing": "error",

It seems this is already included in eslint:recommended. So might overriding
this option be redundant?

     "quotes": ["error", "double", {"avoidEscape": true}],
     "semi": "error",
     "semi-spacing": "error",
     "space-before-function-paren": ["error", "never"],
     "space-in-parens": "error",
     "space-infix-ops": "error",
     "space-unary-ops": "error",
     "spaced-comment": "error",
     "yield-star-spacing": "error"
   }
