Can someone explain what exactly the "\" is doing in this example?
rule 1 /^\(758\)444\(5...\)$/ /\1\2/
thus when you dial 7584445111 it becomes 7585111. I see how the end shows the different sets and that it should become 7585111. why does the "\" need to change the meaning of the "(" ?
it works as an escape character to indicate to take it as a separator and not as a digit or something to match
