Checks that function argument names don’t start with lowercase ‘a’ followed by a capital letter. This is to prevent the use of Hungarian notation whereby the first letter is a prefix that indicates the type or intended use of a variable.

Examples of incorrect code for this rule:

function(aFoo, aBar) {}
(aFoo, aBar) => {}

Examples of correct code for this rule:

function(foo, bar) {}
(foo, bar) => {})
