Pattern: Missing use of isEmpty

Issue: -

Description

Prefer checking isEmpty over comparing collection to an empty array or dictionary literal.

Examples of correct code:

myArray = []


myArray.isEmpty


!myArray.isEmpy


myDict = [:]

Examples of incorrect code:

myArray↓ == []


myArray↓ != []


myArray↓ == [ ]


myDict↓ == [:]


myDict↓ != [:]


myDict↓ == [: ]


myDict↓ == [ :]


myDict↓ == [ : ]
