Rule Details

By default all rules are case insensitive and methods (functions as values) are not ignored.

Warnings:

var obj = {
  c: "foo",
  a: "bar",
  b: {
    e: 1,
    d: 2,
  },
  A: 5
};

OK:

var obj = {
  A: 5,
  a: "bar",
  b: {
    d: 2,
    e: 1,
  },
  c: "foo",
};

OK if ignoreMethods: true

var Foo = {
  b: function() {},
  a: function() {}
};
