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 am not sure how to extract it?

i've to find the sequence of chars ,. inside a json file for example: ":0,.0}},{", so what is the best fitted regex string for it?
i tried /(,.){1,}/g but it doesn't work well.
It's because . is a special character.
const r = /(?:,\.)+/g
console.log('abc,.,.,.def'.match(r)) //[",.,.,."]
you need to escape the .:
/,\./g
