A Step-by-Step Guide to Learning Web Development from Scratch

Introduction:

Web development has become an essential skill in today's digital age, and front-end development, in particular, plays a crucial role in creating engaging and user-friendly websites. However, with so many technologies and frameworks to choose from, it can be overwhelming for beginners to know where to start.

In this article, we'll guide you through the ultimate front-end roadmap that will help you navigate your way to mastering web development. Whether you're a complete beginner or an experienced developer looking to expand your skills, this comprehensive guide will provide you with the essential knowledge and tools you need to become a successful front-end developer.

First Step: The Internet

Understanding how the internet works is essential for front-end developers as they create websites and web applications that are accessed over the internet. A strong knowledge of the internet's underlying technologies, such as HTTP, DNS, and TCP/IP, can help front-end developers troubleshoot issues related to website performance and security.

How does The Internet work?

The internet is like a big, big city with lots of different places to visit, like libraries, stores, and playgrounds. But instead of buildings and streets, the internet is made up of computers and cables that connect them.

When we want to visit a website or send a message to someone far away, our computer sends that message through the internet to the right place. It's like sending a letter through the mail, but it's really, really fast!

To send a message or visit a website, our computer first needs to know where it's going. Just like we need to know the address of a friend's house to visit them, our computer needs to know the address of the website or the person we want to talk to. It's what's called DNS.

DNS and How it works ?

Do you know how we can find a friend's house when we go to visit them? We can ask our parents for the address, and then we use a map or GPS to find the house.

Similarly, when we want to visit a website like YouTube or Google, our computers need to know the website's address so they can find it on the internet. But instead of using a map, our computers use something called DNS.

DNS is like a big phone book for the internet. When we type in a website's name, our computer asks the DNS for the website's address. The DNS looks up the address in its phone book and tells our computer where to find the website.

what is a domain name ?

Have you ever played a game where you have to remember someone's name? A domain name is kind of like a name for a website on the internet.

When we want to visit a website like YouTube or Google, we type in the website's domain name into our computer. For example, the domain name for YouTube is youtube.com.

Just like we can have different names for our friends or pets, there can be lots of different domain names for websites. And just like how we need to remember our friends' names to visit them, our computer needs to remember a website's domain name to find it on the internet.

What is HTTP ?

HTTP stands for Hypertext Transfer Protocol, which is a big, fancy name for a way that computers talk to each other on the internet.

Have you ever played a game where you have to follow some rules to play? HTTP is like a set of rules that computers follow to talk to each other and share information on the internet.

When we visit a website, our computer sends a message to the website's computer using HTTP. The message asks for information, like the pictures and words we see on the website.

The website's computer then sends back a message using HTTP with all the information our computer needs to show us the website. It's like getting a letter back in the mail with all the answers to our questions!

what is hosting ?

Have you ever had a sleepover at a friend's house? Hosting is kind of like having a sleepover, but for websites on the internet!

When we visit a website, the information we see, like pictures and words, comes from a special computer called a server. This computer stores all the information for the website and sends it to our computer so we can see it.

Hosting is when a company or a person lets a website stay on their server, kind of like letting a friend stay at their house for a sleepover. The website can use the space on the server to store all the information it needs, like pictures and words.
