Rules:

• array-iteratee-param-name Validates length of iteratee function's params' names in array methods

  // Iteratee param(s) name too short (at 1:15)
      [1, 2, 3].map(i => i * 10)
  // ---------------^

• function-param-name (unstable) Alike array-iteratee-param-name but validates length of params' names in any function expression, e.g.
  • Function expression function(arg1, ...args) {}
  • Function declaration const f = function(arg1, ...args) {};
  • Arrow function expression const f = (arg1, ...args) => {};
  • Class method class A { method(arg1, ...args) {} }
  • Class property with arrow function expression class A { prop = (arg1, ...args) => {}; }
