I believe you said you wanted this in JavaScript:

var s = 'I am Raktim Banerjee. I love to code.'

var regex = /\b([^!?. ]+)(?:(?: +)([^!?. ]+))*\b([!?.])/g
var m, numSentences = 0, numWords = 0;
do {
    m = regex.exec(s);
    if (m) {
        numSentences++;
        numWords += m[0].split(' ').length
    }
} while (m);
console.log(numSentences + ' sentences, ' + numWords + ' words')

Here is a second iteration. I modified the regex to recognize a few salutations, Mr., Mrs. and Dr. (you can add additional ones), and to add a primitive sub regular expression to recognize an email address. And I also simplified the original regex a bit. I hope this helps (no guarantees because the email check is overly simplified):

var s = 'Mr. Raktim Banerjee. My email address is [email protected].'

var regex = /\b((Mrs?\.|Dr\.|\S+@\S+|[^!?. ]+)\s*)+([!?.])/g
var m, numSentences = 0, numWords = 0;
do {
    m = regex.exec(s);
    if (m) {
        numSentences++;
        numWords += m[0].split(' ').length
    }
} while (m);
console.log(numSentences + ' sentences, ' + numWords + ' words')

Are you looking for something like this :

import re
s1="I am Raktim Banerjee. I love to code. "
s2="Stackoverflow is the best coding forum. I love stackoverflow! "

print(len(re.compile("[^?!.]+").findall(s1))-1,"sentence",len(re.compile("[^\s]+").findall(s1)),"words")

print(len(re.compile("[^?!.]+").findall(s2))-1,"sentence",len(re.compile("[^\s]+").findall(s2)),"words")

Running above outputs:

2 sentence 8 words
2 sentence 9 words
