max-control-nesting

Default severity: warning

Reports control flow nested more than five levels deep. Guard clauses and cohesive helper functions usually make the same decisions easier to follow.

Bad

if first {
  if second {
    if third {
      if fourth {
        if fifth {
          if sixth {
            process()
          }
        }
      }
    }
  }
}

Good

if !ready {
  return
}
for _, item := range items {
  process(item)
}
