SSH installation Node.js
Node.js is a JavaScript running environment based on the Chrome V8 engine, which allows JavaScript to be run, developed and debugged on the server side without the browser. In this article, we will explain how to install Node.js on an SSH terminal.
Step 1: Log in to the SSH terminal
First, you need to log in to your server using an SSH terminal. You can connect to your server using PuTTY (Windows), Terminal (macOS), or ssh (Linux). After successfully logging in, you are in a remote terminal command line environment.
Step 2: Add Node.js source
The developers of the Debian system maintain the apt source of Node.js. We can let the system automatically update and install by adding the address of the source. Enter the following command to add the official Node.js source:
curl -sL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
This command will download and run a shell script. This script will add a Node.js source.
Step Three: Install Node.js
Run the following command to upgrade and install Node.js:
sudo apt-get update sudo apt-get upgrade sudo apt-get install nodejs
During the installation process, the system will install Node on your system .js and npm (Node.js package manager).
You can also check the installed versions of Node.js and npm by running the following commands:
node -v npm -v
Step 4: Use Node.js to run JavaScript files
After installation After finishing Node.js, you can enter the following command to verify whether Node.js was successfully installed:
node -e "console.log('Hello World!')"
This will output the text "Hello World!"
If you want to run the JavaScript file, you can use the following command:
node /path/to/your/file.js
This command will run your file in the terminal.
Conclusion
You can easily install Node.js on an SSH terminal by adding the official Node.js source and installing using apt-get. Additionally, you can use Node.js to run and test JavaScript code from an SSH terminal, as well as use npm to manage your programs and packages.

useState is superior to class components and other state management solutions because it simplifies state management, makes the code clearer, more readable, and is consistent with React's declarative nature. 1) useState allows the state variable to be declared directly in the function component, 2) it remembers the state during re-rendering through the hook mechanism, 3) use useState to utilize React optimizations such as memorization to improve performance, 4) But it should be noted that it can only be called on the top level of the component or in custom hooks, avoiding use in loops, conditions or nested functions.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
