Flattening Conditions

Avoiding deep nesting

Instead of nesting, combine conditions:

// Nested version
if (age >= 18) {
  if (hasTicket) {
    enter()
  }
}

// Flattened version
if (age >= 18 && hasTicket) {
  enter()
}

Flat code is easier to read and debug. Use && to combine conditions that must all be true. Use || for conditions where any can be true.
