Created out of necessity, it is used to build 95.2% (1.52 billion) of websites today, including some of the world’s largest, like Facebook and YouTube. Without it, we would not have popular and useful web apps such as Google Maps and eBay.

5. Server Load
6. Rich Interfaces
7. Extended Functionality
9. Less Overhead
1. Client-side Security
2. Browser Support
3. Lack of Debugging Facility
Though some HTML editors support debugging, it is not as efficient as other editors like C/C++ editors. Also, as the browser doesn’t show any error, it is difficult for the developer to detect the problem.
4. Single Inheritance
5. Sluggish Bitwise Function
6. Rendering Stopped
This is one question that always comes up when it’s time to learn a new programming language. Or it is for me, at least.
To be clear, it’s unlikely to find a programming language on this planet that’s explicitly easy to learn. It’s like learning anything else that’s new to you. You’ll need to work hard to see results.
But the truth is:
Some programming languages are easier to learn than others. This has a lot to do with how you use them and how they read.
For example, Python reads a lot like English, which makes it a beginner-friendly programming language.
I’m not saying HTML or CSS is easy to learn, but they have a different sort of complexity to them.
And that’s what it all boils down to applying what you learn to build programs on your own.
While you’re going through your lectures, take notes. Then, after each lecture, try to use what you just learned to build a small program on your own.
If it feels difficult, look for help in your notes first. They should be good enough to remind you what to do. And if not, take better notes during your next lecture!
But why should you take notes? Can’t you just go back and watch your video lecture again?
You can, yes. But that kind of “monkey see, monkey does” approach won’t help you learn how to code by yourself. May sound harsh, but that’s the reality.
When I started learning to code, I was watching video lectures and repeated whatever exercises they showed. I felt like I was doing progress, but I soon noticed that when I didn’t have those lectures at hand, I couldn’t build anything by myself.
Therefore, don’t underestimate the importance of
- Taking notes and
- Building small projects of your own
Furthermore, you can use a bunch of helpful learning strategies to speed up your learning.
- Focus on one language at a time:
Don’t get distracted by another programming language you find intriguing. Learn your current one well before the next.
- Finish every coding course you start:
When you’ve started one, make sure you finish your online coding course before starting the next one. The lectures build on top of each other, so you want to make it to the last one. That’s where you’ll learn the “good stuff”, i.e. the more advanced lessons.
- Keep your long-term goal in mind:
To speed up your learning, even more, my #1 recommendation is to learn some Computer Science basics before coding.
1. In-line code
In HTML pages each element is defined by means of special tags with specific functions. The integration of JS codes within HTML pages is possible simply by defining one of these tags in any desired position.
These tags can be multiple on the same page, we can also say unlimited.
Furthermore, unlike many other HTML elements, <script> can be inserted in both <body> and <head> without particular distinction. The choice falls on the basis of needs, many scripts in fact need to be executed before rendering or loading the page to work.
In the case of secondary or manual scripts, it is possible (and recommended) to define them in the page footer, in the lowest position, in order to make the page load faster.
2. External code
The URL or path of the file in .js format must be entered in the “src “attribute. The position of the HTML tag follows the same rules of in-line writing as in the previous section.
<! DOCTYPE html>
These rules are easy to remember and we can summarize them in these points:
- Each line of code must end with a semicolon (;).
- JS is case sensitive, that is, it distinguishes between lowercase and uppercase letters (“Name” is different from “name”.
- The custom name of variables, objects and functions cannot start with a number or symbol.
- The separation of words that make up a custom value/name can be defined with the symbol “_” (underscore).
- Furthermore, custom names cannot have spaces between the words that compose them
- It is recommended to use names like my Variable or my_function for example.
- To define text strings or values, they must be enclosed in single (‘) or double (“) quotes, otherwise, they will not be executed and will return errors.
- You cannot give prohibited names to variables or functions. For forbidden we mean those pre-imposed names present in the language that already have established functions such as function, while, for, in, do, return, this, etc …
Keep these concepts in mind but don’t give them too much weight, you will see everything in detail in the following articles.
Therefore pay close attention to writing the code and try to be as orderly as possible following the hierarchy of elements.
If you want to learn more, you can take a look at the “HTML & JS functions ” section of our site, you will find many useful tutorials to start programming with JS in a simple and intuitive way.
