In this lesson, you'll learn about extracting substrings from a string in JavaScript using the method, which is a powerful tool for string manipulation.

Getting a Substring

The best method for getting a substring of a string is . This method allows you to extract a portion of a string based on specified start and end positions.

str.slice(start, end)

The method returns the part of the string from to (but not including) . If the parameter is omitted, extracts to the end of the string.

Let's see it in action with an example:

const exampleString = 'hotdog';

console.log(exampleString.slice(3, 6)); // "dog"

How It Works

• : The zero-based index at which to begin extraction. In this example, corresponds to the character.
• : The zero-based index before which to end extraction. The character at this index will not be included. In this example, corresponds to the character after.

The method is a versatile tool for extracting parts of a string, making it easier to manipulate and analyze text in JavaScript.
