Hello,
In this article, I will teach you how to create a programming library like ReactJS. Basically, I will show you how companies create programming libraries. Then you can upload it to Node Package Manager (npm) so anyone in the world can use it. Without further ado, let's get started.

First, what is a programming library? A programming library (Library) is a collection of programming code that contains specific functions and data types that developers can use in developing their applications and programs without the need to rewrite them from scratch. In other words, a programming library is a collection of programming code that has been compiled together to facilitate the software development process.

To create a programming library and upload it to npm, you can follow the following steps:

(Note that in this article, I will show you how to create a JavaScript library, but you can apply the same steps to any other programming language.)

Step 1: Create a new project. You can create a new project on your computer using different software development tools, such as Visual Studio Code, WebStorm, Atom, or Notepad++.

Step 2: Create a package.json file. You must create a package.json file in the new project folder and fill in the different fields, such as the project name, description, version, author, and follow the latest version of npm.

Step 3: Add programming code. You can add the programming code for the library in JavaScript files in the project folder.

Step 4: Create an account on the npm website and then:

• Login to npm: You must log in to npm using your account.
• Publish the library: You can publish the library on npm using the npm publish command.

These are the basic steps for creating a programming library and uploading it to npm. You can customize these steps according to your project needs and the development tools you are using.
