JavaScript Cut Method

The cut() method is a built-in JavaScript function that can be used to extract a portion of a string and return a new string. The extracted portion can be specified by providing the starting index and the length of characters to be extracted.

Syntax

The syntax of the cut() method is as follows:

string.cut(startIndex, length)

• string: The original string from which a portion is to be extracted.
• startIndex: The index position from which the extraction is to begin.
• length: The number of characters to be extracted.

Example

const str = "JavaScript is awesome";
const newStr = str.cut(0, 10);

console.log(newStr); // Output: "JavaScript"

Output

The cut() method returns the newly extracted string.

Explanation

In the above example, the cut() method is used to extract a portion of the string. The startIndex parameter is set to 0, which means that the extraction will begin from the first character of the string. The length parameter is set to 10, which means that a total of 10 characters will be extracted starting from the first character of the string. The extracted portion is then returned as a new string.

Use

The cut() method can be used to extract a portion of a string based on a specific index position and length of characters.

Important Points

• The cut() method can only be used with string data types.
• The startIndex and length parameters must be integers.
• The cut() method does not modify the original string, instead, it returns a new string.

Summary

The cut() method is a powerful string function in JavaScript that can be used to extract a portion of a string based on a specific index position and length of characters. It is a useful tool for manipulating and working with strings in JavaScript.
