writing it in 1 line doesn't make it better...

not the best solution and not very clever.

• Dont define methods in one line, as it is not very readable
• Use spaces between operators (+) and parameters to make the code more readable
• Using a variable like sum for the result of the addition makes the code more self explenatory

Okay, thanks for that !

Great solution but it has me a little confused.

How does the last section of code convert the sum into binary ?

Thanks

Love this. Clearly written. Clean. Maybe consider renaming your "removed" var to "moved".

How long did it take you to write this? Just curious.

There're already enough.

Thanks man, this is really helpful for noobies like me.

Putting '+' before a string which represents a number will coerce that string into a number, but that's not best practice as it isn't as readable as other methods.

What is the reason you put base ten in the parseInt function?

Wouldn't that depend on what your expected behavior on having a non-integer input is? Depending on context, returning without raising an exception could just create problems.
