Frontend Developers skills you must know ✈✨

✅**1.HTML,CSS and JS**
Front-End development without HTML, CSS, and JavaScript is impossible. They play a vital role in making the UI look dynamic and feel great. Let’s discuss each of these a bit more clearly.  
**HTML** (to structure web pages)
**CSS**(to add beauty to websites)
**JavaScript** (to program and make websites dynamic and responsive)

✅**2.Front-End Frameworks**
Frameworks are the tools providing components that are customized to speed up development, and may also include a library. It is a platform/tool to build the front end of your website. In simple terms, frameworks build the layout structure of a building. You should be familiar with the work and ways to use it for faster coding
There are many front-end frameworks like React, Angular, and Vue.js, but React is the most popular, easy, trendy, and most-used framework. 

✅**3. Responsiveness**
When it comes to web development, frontend developers should be aware of the term “responsiveness” which means the websites should be responsive and viewed on any device whether it would be a mobile, laptop, phone, tablet, etc. The web page should have the ability to adjust itself to the device (laptop, tablet, mobile, etc.) used by the users. Based on the platform, the website should adapt appropriately and adjust its appearance and layout to match the device screen’s resolution. 
The in-built features of CSS frameworks like Tailwind and Bootstrap help you to make websites more responsive for all device sizes with a little less work.

✅**4. Version Control Systems**
Version Control System is a system that keeps a record of code changes to a file or set of files over time. They are generally software tools helping the software team to manage changes to source code while also revealing who made which modifications. It is a very helpful skill every front-end developer must-have.

Git (Global Information Tracker) is the most popular, open-source, and distributed version control system where an entire repository can be changed by each user on their system. It uses a command line to install in your system and using Git, it’s easy to undo changes and back and forth with a clear explanation of changes made.  

✅**5. CSS Pre-Processors**
CSS Preprocessor is an advanced version of CSS. It is a program that lets you generate CSS from the preprocessor’s unique syntax. It maintains the code more easily and the long run makes it easy to edit. CSS preprocessors like nesting selector and inheritance selector are some features that don’t exist in pure CSS that can be used which makes the code more organized and more readable by shaving off some of the lines. Writing repetitive code is time-consuming which is more common in working with just CSS. This can be avoided by speeding up CSS coding by using CSS preprocessors which are another element that any front-end developer must use. 


✅**6. Command Line** 
The CLI or Command Line Interface is a text-based application for managing files on your system. It plays an important role in web development, also an all-purpose GUI (Graphical User Interface) has limitations for some specific applications. You enter some commands in a terminal and it performs some actions which help in getting some results when working with web development. You should also know the properties of the Shell to access operating system functions via a text interface.  

It helps you attain faster management. To conclude, command-line tools open up new ways to make your production and delivery of code in HTML, CSS, and JavaScript languages more efficient.

✅**7. Testing and Debugging**
After the development process of a web application, the important aspect comes is testing and debugging to make sure that the results are bug-free to provide a good experience to its user. The chances of getting no bugs in the software development process are very rare and for that, the process of testing and debugging is a mandatory one. It’s an additional skill for any front-end developer to develop the quality of your website. Now let’s get clear with the difference between testing and debugging:

Testing is a software practice to ensure the quality and functionality of a web application. Several factors like usability, and compatibility has to be kept in mind while testing. The primary goal of a tester should be that the application should run smoothly without any hindrance. There are various types of testing some of them include Unit testing and Component testing.
Unit Testing tests individual blocks of code, where you check that the website should behave in a proper way as designed to be. Every action is being performed like clicking a button navigates to another page if it has to.
Component Testing examines a particular component and checks individual parts of an application. Here, real data of the written code are tested instead of dummy data by the developers.
There are various other types of testing as well which enhance the working of a website. Other types of testing are Integration Testing, Alpha Testing, Beta Testing, and many more.

Debugging is a process of fixing errors (bugs) found during testing in a web application. This process involves identifying the bug, finding the source of it, and rectifying the problem to make the program error-free and proper functioning of the website. Steps include identifying the error, finding the location, analyzing it, fix and validating it. This process can be done manually or with automated tools. It’s an essential skill needed in a front-end developer as it finds and fixes errors in source code. Also, proper use of breakpoints should be followed to see the flow of code and which easily detects errors line-by-line which helps in understanding the execution of the code.

✅**8. Web Performance Optimization**
Web optimization generally refers to the time taken by any site to load. Optimizing web pages improves speed, scalability, and smoothness which is necessary for any web application. A website that takes more than 3 seconds to load is generally considered to be less optimized. Multiple factors which cause optimization issues are:  

global convergence,
local convergence,  
role of the underlying optimization method,
role of the multigrid recursion,
properties of the optimization model.
Steps to improve performance of web:

Minimizing the use of CSS and JavaScript wherever possible.
Using optimized images.
Remove unwanted plugins
If your website is having trouble getting loaded or any such issues, there are steps to improve it.  
A good hosting provider.

✅**9.DOM Manipulation** 
DOM (Document Object Model) is a programming interface for web documents. It represents the document as nodes and objects, where programming languages can interact with the page. Using programs, you can change the document structure, style, and content of a web page.  

DOM manipulation is interacting with the DOM API to change or modify the HTML document such as adding, removing, editing, and moving elements that are rendered on a web browser. One of the first things to learn when learning JavaScript for web browsers should be DOM manipulation. It represents the structure and the content of any web document which also include styles and HTML part. It allows you to create responsive web experiences. To manipulate an element inside the DOM, the first thing you need to do is to select it and store a reference to it inside a variable. Without refreshing a page, you can update the data and change the layout of the page, and create customizable applications.  

✅**10. RESTful APIs**
REST which stands for representational state transfer uses API (known as RESTful API) which is an application programming interface that allows interaction with RESTful web services. It uses HTTP (HyperText Transfer Protocol) requests to access and manage data. Several commands like GET, PUT, POST, and DELETE data types mean reading, updating, creating, and deleting operations.  

Using GET requests to retrieve data,
POST request to create a data,
PUT request to update a data,
DELETE request to delete one in an application.
All HTTP methods can be used in API calls. A well-designed REST API is the same as a website running in a web browser with built-in HTTP functionality.

🔴That's great✨ if you have it till end😀 !
**_Skills are not built in 1 day or 1 week it take lots of practice and implementation in the real-time project responsive websites and hosting them as well.
Just keep going with your passion💜_
