I am trying to write a Java Script function that should enclose all the special characters in the given String in a bracket like following -
Input ===> Output
123##$, ====> 123[#][#][$][,]
Changing All the special characters to certain String [ _ in this case] is easy -
string = string.replace(/[^a-zA-Z0-9]/g,'_');

I was wondering, what is the best way to implement the following case:
vm.elasticQuery = userQuery.replace(/~='[a-zA-Z]+'/g,':*[a-zA-Z]+*')
In other words, I would like to replace every pattern that looks like this ~='SomeLetters' to a pattern that looks like this :*SomeLetters*. Take into account that I do not want to remove/change the alphabets but only the outside.
Your help is appriciated.

I have this regular expression that tokenizes calculator input strings like 12+3.4x5 to 12,+,3.4,x,5
The regular expression used is
\d+\.?\d+|[\+-÷x]
I get an unexpected match with ^ and letters.
Regex solution, although there's probably a cleaner way of writing this if someone could point it out?
(\d+\.?\d+|\d+|(\+|-|÷|x))
