JavaScript Split Regular Expression keep the delimiter

Question

Using JavaScript I\'m trying to split a paragraph into it\'s sentences using regular expressions. My regular expression doesn\'t account for a sentence being inside bracket

Answer 1

use the (?=pattern) lookahead pattern in the regex example

var string = '500x500-11*90~1+1';
string = string.replace(/(?=[$-/:-?{-~!"^_`\[\]])/gi, ",");
string = string.split(",");

this will give you the following result.

[ '500x500', '-11', '*90', '~1', '+1' ]

Can also be directly split

string = string.split(/(?=[$-/:-?{-~!"^_`\[\]])/gi);

giving the same result

[ '500x500', '-11', '*90', '~1', '+1' ]
