How do you remove the last 3 elements of a string in JavaScript?

In this article, you will learn how to remove the last 3 elements of a string using JavaScript built-in method substring(). This can be accomplished with some simple code, which we'll explain here.

1. To start, you'll need to create a variable for your string and assign it the desired value.

   <script>
     let myString = "This is a sample string";
   </script>

2. Next, you will use JavaScript's built-in substring() method to remove the last three characters from your string.

   <script>
     let myString = "This is a sample string";
     let newString = myString.substring(0,myString.length - 3);
     console.log(newString)
   </script>

   The first argument passed into substring() specifies where in our original text we want our new truncated version of it to begin (in this case 0), while the second argument indicates how many characters should remain after cutting off what comes after it (3).
