Count Total Punctuations in a String in JavaScript

In the English language, all these characters are considered as punctuations −

'!', "," ,"\'" ,";" ,"\"", ".", "-" ,"?"

We are required to write a JavaScript function that takes in a string and count the number of appearances of these punctuations in the string and return that count.

Example

Let’s write the code for this function −

const str = "This, is a-sentence;.Is this a sentence?";
const countPunctuation = str => {
   const punct = "!,\;\.-?";
   let count = 0;
   for(let i = 0; i < str.length; i++){
      if(!punct.includes(str[i])){
         continue;
      };
      count++;
   };
   return count;
};
console.log(countPunctuation(str));

Output

The output in the console: −
