JavaScript’s trimEnd() method, alternatively known as trimRight(), is utilized to remove whitespace from the end of a string. This includes all sorts of whitespace characters (like spaces, tabs, and line breaks) found at the string’s end. It’s important to note that trimEnd() doesn’t alter the original string; instead, it returns a new string with the whitespace at the end removed. The trimEnd() method in JavaScript is a specialized tool tailored for scenarios necessitating the removal of unwanted whitespace at the conclusion of strings.
Syntax:
The syntax of the trimEnd() method is quite straightforward:
string.trimEnd()
This method doesn’t require any parameters and it returns a new string with the trailing whitespace eliminated.
Examples and execution:
The examples provided can be executed in any standard JavaScript environment, including browser consoles, online code playgrounds, or a local Node.js setup.
Basic usage:
let farewell = "Goodbye, World! ";
let trimmedFarewell = farewell.trimEnd();
console.log(trimmedFarewell); // Outputs: "Goodbye, World!"
function cleanInput(input) {
let cleanedInput = input.trimEnd();
console.log("Cleaned input:", cleanedInput);
}
let userInput = "Learning JavaScript is fun! ";
cleanInput(userInput); // Outputs: "Cleaned input: Learning JavaScript is fun!"
let string = " JavaScript is ubiquitous! ";
let processedString = string.trimEnd().toLowerCase();
console.log(processedString); // Outputs: " javascript is ubiquitous!"
function prepareComment(comment) {
let preparedComment = comment.trimEnd();
// Further comment processing
console.log("Prepared comment:", preparedComment);
}
let userComment = "Can't wait for the next JavaScript update! ";
prepareComment(userComment); // Outputs: "Prepared comment: Can't wait for the next JavaScript update!"Get more articles on Java Script
