Common Refactoring Technicques for Critice Code

Tidak all refactorin techques are equallyy safe. Favor those that are mekanicrel and repsible:

  • Pertama, FLT: 0 = 33; Extract Method = 1; FLT: 1 ASA3; ASA3; - Move a block of codite into a new method to improve readability. Ensure the extracted doeds not add side effects.
  • Pertama, FLT: 0 = 33. Rename Variable or Function; FLT: 1: 33; - Improve clarity tanpa refereno reference. Use IDE-WERAME REPROTING TO ALL reference.
  • Pertama; FLT: 0; 33; Replace Magic Number with Symbolt Constant Constant; FLT: 1 FLT: 1 AF3; - Eliminate hard- codeals thatt may cause consusion maintenanpe.
