π¦π Best JavaScript frameworks / libraries for front-end development
1) React
React is not really a framework, but rather a JavaScript library for building user interfaces.
It is open source and maintained by Facebook and the individual developer community.
Some of its features include the following:
Provides reactive, customizable and reusable components
Uses virtual DOM
Very fast
Component based
One-way data binding
Reusable code
Behind it is a vibrant and thriving ecosystem.
Convenient state management
Installation and use
π¦React can be used in two different ways:
Through CDN
Using Node.JS
Through CDN
You can refer to their official website for a script link that you can include in the title tag in your HTML markup.
Choose links based on your purpose.
For example, when used in a development environment:
<script crossorigin src="https://unpkg.com/react@16/umd/react.development.js"></script>
<script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script>
And for production:
<script crossorigin src="https://unpkg.com/react@16/umd/react.production.min.js"></script>
<script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.production.min.js"></script>
2) Using Node.JS
I am assuming you have NodeJS installed already.
To install React, just enter the following command.
sudo npm i -g create-react-app --save-dev
After the installation is complete, enter the following command
create-react-app my-first-react-application
The above command will install all the prerequisite libraries required for React to work properly, including the development server, webpack, and babel.
Go to your application folder my-first-response-application and run the following command
npm start
The above command will start the development server on port 3000.
And, when you access the IP address of your server on port 3000, you should have a welcome page
3) Vue.js
Vue.js is a progressive JavaScript framework for building interactive user interfaces and single page applications.
This is a presentation-oriented framework with a core library.
Vue is popular because it supports single page apps.
Unlike React, Vue uses raw HTML, not JSX.
Vue.js is open source and was originally created by Evan Yu and released publicly in February 2014.
Below are some of the features.
It provides reactive and composite view components.
Uses virtual DOM
Focuses on the core library (e.g. routing and state management)
CSS Scope Handled Without CSS-In-J
One-way binding inside components.
Support for major add-ons
Reusable code

BASIC LINUX:
1) Linux is just the core
All Linux distributions include GUI system, GNU utilities, installation and management tools, GNU c/c++ compiler, editor (vi), and various applications such as OpenOffice, Firefox.
2) The UNIX operating system is considered a complete OS, because everything comes from one vendor.
3) Security and firewall
Linux comes with open source firewall tools based on Netfilter and IPTables, which can protect your servers and desktops from hackers and hackers. The UNIX operating system comes with its own firewall product.
4) Backup and restore
UNIX and Linux have their own set of tools for backing up data to tape and other backup media. However, Linux and UNIX share some common tools, such as tar, dump/restore, and cpio.
5) What is the core of the Linux operating system?
Answer: The kernel is the core of the Linux operating system.
6) What is the Linux kernel?
Answer: The kernel is the heart of the operating system. It acts as a bridge between software and hardware. If the software requests the hardware, the kernel will pass data between the software and the hardware. For example, if you want to play a song, you should start the default player, it will ask the kernel to play a song, and now the kernel will contact the hardware for permission or for hardware components, just like you plug in any headset. Device. Most Android phones use the Linux kernel.
Yes, the kernel can be edited because it is released under the General Public License.
7) What is BASH?
Answer: Bash is a Unix shell and command processor written by Brian Fox for the GNU project. It is free software and can replace Bourne Shell. This is an interpreted, uncompiled process that can also be run in a terminal window. This allows users to write commands and cause actions. Bash can read commands from Shell scripts.

π¦ How many types of shells are there in Linux?
They are the five Shells in Linux:
1) C Shell (csh): Similar to C grammar, and provides spell checking and job control.
Korn Shell (ksh): is a high-level programming language Shell.
2) Z Shell (Zsh): It provides some unique properties, such as observing login/logout monitoring, file name generation, startup file, and end comment.
3) Bourne Again Shell (bash): This is the default setting of the Linux distribution.
4) Friendly interactive Shell (Fish): It provides web-based configuration, automatic suggestions, etc.

What are the basic components of Linux?
1) Kernel: It is the core component of Linux, which acts as an interface between software and hardware.
2) Shell: It acts as an interface between the user and the kernel.
3) GUI: It stands for Graphical User Interface, which is another way for users to interact with the system. But this is different from images, buttons, and text boxes for interaction.
4) System Utilities: These are software functions that allow users to manage the computer.
5) Application: A set of functions designed to perform a set of tasks.
