JavaScript String padEnd() Method

The padEnd() method in JavaScript is used to pad a string with another string until it reaches the given length. The padding is applied from the right end of the string.

Syntax:

string.padEnd( targetLength, padString );

Parameters:

This method accepts two parameters as mentioned above and described below:

• targetLength: It is the length of the final string once the original string has been padded. If the value is less than the original string length, then the original string is returned.
• padString: It is the string that is to be padded with the original string. If this value is too long to be within the targetLength, it is truncated.

Return Value:

It returns the final string that is padded with the given string of the given length. 

Example 1: This example uses the padEnd() method to pad strings into another string. 

// Function to implement  padEnd method
function padStrings() {
    // Input methods
    exString = "Hello";
    exString2 = "Geeks";

    // Implement padEnd methods to add symbols at end
    output = exString.padEnd(12, "$");
    output2 = exString2.padEnd(12, "Geeks");

    // Display output
    console.log(output);

    console.log(output2);
}
// Function call
padStrings()

Hello$$$$$$$
GeeksGeeksGe

Example 2: This example uses the padEnd() method to pad numbers into another number. 

// Function to implement padEnd method
function padNumbers() {
    // Input numbers
    exNumber = 1234;
    exNumber2 = 99;

    // Implement padEnd 
    output = String(exNumber).padEnd(8, "0");
    output2 = String(exNumber2).padEnd(8, "**");

    // Display output number
    console.log(output);
    console.log(output2);
}

// Function call 
padNumbers()
