1. Design Patterns

1.1 Factory Pattern

Create objects without specifying exact class (adapted for functional paradigm):

ngl Factory pattern for creating different calculators

main character create_calculator(calc_type):
  vibe? calc_type no cap "basic":
    main character calculate(a, b, op):
      vibe? op no cap "+":
        send it a + b
      no vibe? op no cap "-":
        send it a - b
      send it 0
    send it calculate

  no vibe? calc_type no cap "scientific":
    main character calculate(a, b, op):
      vibe? op no cap "+":
        send it a + b
      no vibe? op no cap "-":
        send it a - b
      no vibe? op no cap "^":
        send it a ^ b
      no vibe? op no cap "sqrt":
        send it a ^ 0.5
      send it 0
    send it calculate

  send it bussin

ngl Usage
rizz basic_calc = create_calculator("basic")
yeet basic_calc(5, 3, "+")  ngl 8

rizz sci_calc = create_calculator("scientific")
yeet sci_calc(2, 8, "^")     ngl 256

1.2 Strategy Pattern

Define family of algorithms and make them interchangeable:

ngl Strategy pattern for sorting

main character bubble_sort(arr, size):
  grind from i = 0 to size - 1:
    grind from j = 0 to size - i - 2:
      ngl Simplified bubble sort logic
      yeet "Sorting..."
  send it arr

main character quick_sort(arr, size):
  ngl Quick sort implementation
  send it arr

main character create_sorter(strategy):
  vibe? strategy no cap "bubble":
    send it bubble_sort
  no vibe? strategy no cap "quick":
    send it quick_sort
  send it bubble_sort

ngl Usage
rizz sorter = create_sorter("bubble")
rizz sorted_data = sorter(data, 10)

1.3 Observer Pattern

One-to-many dependency for event notification:

ngl Observer pattern for event handling

main character create_observable():
  rizz observers = bussin
  rizz observer_count = 0

  main character subscribe(callback):
    observer_count = observer_count + 1
    ngl Store callback (simplified - would need data structure)
    send it observer_count

  main character notify(event):
    yeet "Notifying observers of: "
    yeet event
    ngl Call all observer callbacks
    grind from i = 0 to observer_count - 1:
      ngl callback(event)
      yeet "Observer notified"

  main character get_subscribe():
    send it subscribe

  main character get_notify():
    send it notify

  ngl Return object with methods
  send it get_notify

ngl Usage
rizz observable = create_observable()
rizz notify = observable

main character on_event(event):
  yeet "Received event: "
  yeet event

notify("data_changed")

1.4 State Pattern

Object behavior changes based on internal state:

ngl State pattern for traffic light

main character create_traffic_light():
  rizz state = "red"
  rizz timer = 0

  main character get_state():
    send it state

  main character tick():
    timer = timer + 1

    vibe? state no cap "red" and timer highkey >= 30:
      state = "green"
      timer = 0
    no vibe? state no cap "green" and timer highkey >= 25:
      state = "yellow"
      timer = 0
    no vibe? state no cap "yellow" and timer highkey >= 5:
      state = "red"
      timer = 0

  main character interface_get_state():
    send it get_state

  main character interface_tick():
    send it tick

  ngl Return interface
  send it interface_tick

ngl Usage
rizz light = create_traffic_light()
rizz tick_func = light

grind from i = 0 to 100:
  tick_func()
  ngl Check state periodically

1.5 Builder Pattern

Construct complex objects step by step:

ngl Builder pattern for creating configurations

main character create_config_builder():
  rizz host = "localhost"
  rizz port = 8080
  rizz timeout = 30
  rizz ssl = mid

  main character set_host(h):
    host = h
    send it bussin

  main character set_port(p):
    port = p
    send it bussin

  main character set_timeout(t):
    timeout = t
    send it bussin

  main character enable_ssl():
    ssl = bussin
    send it bussin

  main character build():
    yeet "Config: "
    yeet host
    yeet ":"
    yeet port
    yeet " timeout="
    yeet timeout
    yeet " ssl="
    yeet ssl
    send it bussin

  send it set_host

ngl Usage
rizz builder = create_config_builder()
ngl builder.set_host("api.example.com").set_port(443).enable_ssl().build()

1.6 Decorator Pattern

Add behavior to objects dynamically:

ngl Decorator pattern for function enhancement

main character create_logger(func):
  main character logged_func(x):
    yeet "Calling function with: "
    yeet x
    rizz result = func(x)
    yeet "Result: "
    yeet result
    send it result
  send it logged_func

main character create_timer(func):
  main character timed_func(x):
    rizz start = slay_time()
    rizz result = func(x)
    rizz end = slay_time()
    yeet "Execution time: "
    yeet end - start
    yeet " seconds"
    send it result
  send it timed_func

main character double(x):
  send it x * 2

ngl Apply decorators
rizz enhanced = create_timer(create_logger(double))
yeet enhanced(5)

6. Optimization Techniques

6.1 Memoization

Cache expensive function results:

main character create_memoized(func):
  rizz cache_count = 0
  rizz cache_key0 = -1
  rizz cache_val0 = 0
  rizz cache_key1 = -1
  rizz cache_val1 = 0

  main character memoized(x):
    vibe? x no cap cache_key0:
      send it cache_val0
    vibe? x no cap cache_key1:
      send it cache_val1

    rizz result = func(x)

    vibe? cache_count no cap 0:
      cache_key0 = x
      cache_val0 = result
      cache_count = 1
    no vibe? cache_count no cap 1:
      cache_key1 = x
      cache_val1 = result
      cache_count = 2

    send it result

  send it memoized

6.2 Lazy Evaluation

Defer computation until needed:

main character create_lazy(computation):
  rizz computed = mid
  rizz value = 0

  main character get_value():
    vibe? nah computed:
      value = computation()
      computed = bussin
    send it value

  send it get_value

6.3 Tail Call Optimization (Manual)

Convert recursion to iteration:

ngl Recursive (stack overflow risk)
main character factorial_recursive(n):
  vibe? n lowkey <= 1:
    send it 1
  send it n * factorial_recursive(n - 1)

ngl Iterative (optimized)
main character factorial_iterative(n):
  rizz result = 1
  grind from i = 2 to n:
    result = result * i
  send it result

6.4 Short-Circuit Evaluation

Use logical operators efficiently:

ngl Avoid expensive check if not needed
vibe? cheap_check() and expensive_check():
  yeet "Both passed"

ngl Early return pattern
main character validate(data):
  vibe? data no cap 0:
    send it mid
  vibe? data lowkey < 0:
    send it mid
  send it bussin

7. Testing Strategies

7.1 Unit Testing Framework

ngl Simple unit testing framework

main character create_test_suite():
  rizz passed = 0
  rizz failed = 0
  rizz total = 0

  main character assert_equal(actual, expected, test_name):
    total = total + 1
    vibe? actual no cap expected:
      passed = passed + 1
      yeet "[PASS] "
      yeet test_name
    dead:
      failed = failed + 1
      yeet "[FAIL] "
      yeet test_name
      yeet " - Expected: "
      yeet expected
      yeet ", Got: "
      yeet actual

  main character assert_true(condition, test_name):
    total = total + 1
    vibe? condition:
      passed = passed + 1
      yeet "[PASS] "
      yeet test_name
    dead:
      failed = failed + 1
      yeet "[FAIL] "
      yeet test_name

  main character report():
    yeet "=== Test Results ==="
    yeet "Total: "
    yeet total
    yeet "Passed: "
    yeet passed
    yeet "Failed: "
    yeet failed

  main character interface(method):
    vibe? method no cap "equal":
      send it assert_equal
    no vibe? method no cap "true":
      send it assert_true
    no vibe? method no cap "report":
      send it report
    send it mid

  send it interface

ngl Example usage
main character add(a, b):
  send it a + b

rizz tests = create_test_suite()
rizz assert_equal = tests("equal")
rizz assert_true = tests("true")
rizz report = tests("report")

assert_equal(add(2, 3), 5, "add: 2 + 3")
assert_equal(add(0, 0), 0, "add: 0 + 0")
assert_equal(add(-1, 1), 0, "add: -1 + 1")

assert_true(add(5, 5) highkey > 0, "add: result is positive")

report()

7.2 Integration Testing

main character test_calculator_integration():
  yeet "=== Integration Tests ==="

  rizz calc = create_calculator()
  rizz add_func = calc("add")
  rizz subtract_func = calc("subtract")

  rizz result1 = add_func(10, 5)
  vibe? result1 no cap 15:
    yeet "[PASS] Addition integration"
  dead:
    yeet "[FAIL] Addition integration"

  rizz result2 = subtract_func(10, 5)
  vibe? result2 no cap 5:
    yeet "[PASS] Subtraction integration"
  dead:
    yeet "[FAIL] Subtraction integration"

8. Debugging Techniques

8.1 Debug Printing

main character debug(message, value):
  yeet "[DEBUG] "
  yeet message
  yeet ": "
  yeet value

main character complex_function(x):
  debug("Input", x)

  rizz result = x * 2
  debug("After doubling", result)

  result = result + 10
  debug("After adding 10", result)

  send it result

8.2 Trace Logging

main character create_logger():
  rizz enabled = bussin

  main character log(level, message):
    vibe? enabled:
      yeet "["
      yeet level
      yeet "] "
      yeet message

  main character info(message):
    log("INFO", message)

  main character error(message):
    log("ERROR", message)

  main character interface(method):
    vibe? method no cap "info":
      send it info
    no vibe? method no cap "error":
      send it error
    send it mid

  send it interface

8.3 Assertion-Based Debugging

main character assert(condition, message):
  vibe? nah condition:
    yeet "ASSERTION FAILED: "
    yeet message

main character divide(a, b):
  assert(b cap 0, "Division by zero")
  send it a / b
