## Why is this an issue?

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
      ...
    }
