A boolean literal can be represented in two different ways: true or false. They can be combined with logical operators
(!, &&, ||, ==, !=) to produce logical expressions that represent truth values. However, comparing a boolean literal to a
variable or expression that evaluates to a boolean value is unnecessary and can make the code harder to read and understand. The more complex a
boolean expression is, the harder it will be for developers to understand its meaning and expected behavior, and it will favour the introduction of
new bugs.
Exceptions
The use of literal booleans in comparisons which use identity operators (=== and !==) are ignored.
