        Why is this an issue?

        How can I fix it?

        Nested code - blocks of code inside blocks of code - is eventually necessary, but increases complexity. This is why keeping the code as flat as possible, by avoiding unnecessary nesting, is considered a good practice.

        Merging if statements when possible will decrease the nesting of the code and improve its readability.

        Code like

        if (condition1) {
          if (condition2) {             // Noncompliant
            /* ... */
          }
        }
        

        will be more readable as

        if (condition1 && condition2) { // Compliant
          /* ... */
        }
