Example
var originalString="JJJJOHHHHNNNSSSMMMIIITTTTHHH"; var regularExpression=/(.)\1*/g; console.log("The original string="+originalString); var splitting=originalString.match(regularExpression); console.log("After splitting the original string="); console.log(splitting);
To run the above program, you need to use the following command −
node fileName.js.
