Question

Can anybody help me writing a regular expression to replace these characters with a empty string. Character list is given below.

public static char[] delimiters = { ' ', '\r', '\n', '?', '!', ';', '.', ',', '`', ':', '(', ')', '{', '}', '[', ']', '|', '\'', '\\', '~', '=', '@', '>', '<', '&', '%', '-', '/', '#' };

Here’s the regex you want:

var re = /[ \r\n?!;.,`:(){}\[\]\|\'\\~=@><&%-\/#]/g;

For example:

var test = "j a\nv\ra?s!c;r.i,p`t:I(s)A{w}e[s]o|m'e\\~=@><&%-/#";
test.replace(re, '')

>>> "javascriptIsAwesome"

FYI, the general notation for this sort of thing in regular expressions is “/[…]/” – means, “match any character inside the brackets”
