🚫 Don’t nest "If-else Statements"

Key Takeaways

you are using IF else statements wrong look at this code can you see the problem with using IF else like this in the start car function we are checking two conditions back to back we first check if the seat belt is on then we check if the road is clear if both the conditions are met we start the car if not we do something else and with so many nested statements it's really hard to tell what happens in which condition it's obvious that the readability of this code is really bad how can you fix this well you can use guard claws here flip the condition and check if the seat belt is not on if it's not on write a debug statement in return now check if the road is not clear add a debug statement and return if none of these conditions are met then simply start the car
