JS.BASE.NO.ARRAY.CONSTRUCTOR

Use of the Array constructor to construct a new array is generally discouraged in favor of array literal notation because of the single-argument pitfall and because the Array global may be redefined. The exception is when the Array constructor is used to intentionally create sparse arrays of a specified size by giving the constructor a single numeric argument.

When Not To Use It

This rule enforces a nearly universal stylistic concern. That being said, this rule may be disabled if the constructor style is preferred.
