Return of boolean literal statements wrapped into if-then-else flow should be simplified.

Note that if the result of the expression is not a boolean but for instance an integer, then double negation should be used for proper conversion.

if (expression) {
  return true;
} else {
  return false;
}

or

if (expression) {
  return true;
}
return false;

Compliant Solution

return expression;

or

return !!expression;
