Count sentences in string with Javascript

In this article, you will learn how to count how many sentences are present in a string using Javascript.

Suppose, you want to create a online sentences or words counter using Javascript, then you should use the below method.

<script>
 const myText = "This is a paragraph. Is it?";
 const stop = /[.!?]/;
 const sentence = myText.split(stop);
 console.log(sentence.length - 1);
</script>

1. First, we will create a variable with two sentences (according to your choice).
   

   const myText = "This is a paragraph. Is it?";

2. We have to create one more variable for the stop keywords (question mark, full stop, exclamation mark).
   

   const stop = /[.!?]/;

3. Now, we will split the sentences using the Javascript split() method and store in a variable.
   

   const sentence = myText.split(stop);

   The sentence variable will return the following array.

   🔽Array
    0:"This is a paragraph"
    1:"Is it"
    2:" "
    length:3
     

4. Now, we can use the length property of the array to get the number of how many sentences are in the string.
   

   console.log(sentence.length - 1);
