The lambdas don’t capture the value of
i at each loop iteration, they capture the variable itself. By the time you call the functions, the loop has finished, and i is left at its final value, 2.This is called late binding and can cause unexpected behavior when creating closures inside loops.
So as a quick tip, Bind the current value at definition time using a default argument(like shown in the second image) Then each lambda remembers its own
i value independently.
