in thread "While" effect on regex?

you mean that the while loop executes for each match of /g?
so if /g matches 2 times then the while block will be executed twice?

    Indeed, the second loop will be executed once for each match.


    A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
