Hướng dẫn JavaScript: Tách chuỗi & Chuyển đổi số với Split + Map

Gặp chuỗi "1,2,3"? Muốn thành mảng số [1,2,3]?
➊ Dùng .split(",") để tách thành ["1","2","3"]
➋ Thêm .map(Number) chuyển thành số
⚠️ Thiếu map(Number): "1"+"2" = "12" (nối chuỗi)
✅ Có map(Number): 1+2 = 3 (tính toán đúng)
Mẹo: map(Number) ngắn gọn hơn map(x=>Number(x))

After writing the data, do some 'uchawi', manually #HapaUjanjaTu #keyprogramming #5021tips #ecu #programmingtips #carkeys #howitsdone #magari #autoelectronics #carkeyprogramming #lostkeys

L) Le mot de passe change lorsque le moteur est autorisé à démarrer👌!
K) Parce que la clé est retirée, le périphérique (K) est utilisé pour jouer le rôle de la modification du mot de passe🫣

Remember, #HapaUjanjaTu, Microprocessors typically require external peripherals👌!
Alafu,
Microcontrollers integrate the peripherals onto a single chip😉! #programmingtips #5021tips #techtips #repairtips #electronicsrepair #motherboardrepair #umeme
