Hi. So i am on the ‘Spinal Tap Case’ challenge and i am stucked. I sneak peaked the solutin and i cannot really understand the regex which replaces UpperCase with space.
The first regex was easy enough for me to figure it out:
let regex = /[\W\s+_]/g;.
But the regex i dont understand is this one:
str = str.replace(/([a-z])([A-Z])/g, "$1 $2");
Can someone explain me how this works exactly? Which part of the regex identifies the space we add?
