You can install @akcybex/jstr using npm:

npm i @akcybex/jstr -S

Using Yarn

Alternatively, you can use Yarn to add the package:

yarn add @akcybex/jstr

Usage in Node.js

After installing, you can use @akcybex/jstr in your Node.js application:

import JStr from "@akcybex/jstr";

const result = JStr.of("hello").repeat(3).upper().toString();
console.log(result); // Outputs: 'HELLOHELLOHELLO'

Available Methods

Note

Methods with ✔✔ mark are included in the library and tested as well.

Strings

A string is a fundamental data type in programming used to represent a sequence of characters. It stores and manipulates text data, and string operations are typically performed using methods or functions provided by the programming language or relevant libraries. Common operations include concatenation, searching, replacing, and formatting strings.

Fluent String

Fluent strings provide a more fluent, object-oriented interface for working with string values. This paradigm allows you to chain multiple string operations together, creating a more readable syntax compared to traditional string operations. Each method call returns a new fluent string object, enabling you to seamlessly chain operations while maintaining clarity and conciseness in your code.
