如何减少长布尔表达式的复杂度？

Question

I have a boolean expression to evaluate that is pretty long with a lot of different cases:

return (a && b && c) ||
(d && e && f) ||
...

This should return a boolean!

a, b, c, d, e and f being simple equality comparison and being all different. This continues for 12 lines and gives me a Cyclomatic Complexity of 44

I tried to look at the Map object in order to reduce the complexity but did not find a way to do it.

How could I reduce the complexity of such an expression ?

Answer 1

You can not reduce the complexity of the given expression.

A slower approach, but maybe a little more structured, is to group the expressions and evaluate with Array#some for the outer array and Array#every for the inner arrays with a short circuit.

return [[a, b, c], [d, e, f]].some(a => a.every(Boolean));
