Day 2 - Q. Clean the following text and find the most frequent word (hint, use replace and regular expressions).

[kattasahan]

For above question i used so many functions and regular expressions to solve it, but as question is in Day-2, i think those are not ideal methods to solve

My Solution :

sentence
    .split(" ")
    .reduce((arr, e) => {
      let str = e.match(/[a-zA-Z]+/g);
      arr.push(str.join(""));
      return arr;
    }, [])
    .join(" ")

If anybody having a short and sweet solutions, Please share here...

Thanks in advance.

We can replace the string with regular expression just as the hint mentioned. Here is my solution:

sentence.replace(/[^a-zA-Z0-9.,?!'\s]/g, '');
