Which is easier to learn, H5 or JS?

The learning difficulty of H5 (HTML5) and JS (JavaScript) is different, depending on the requirements. A simple static web page only needs to learn H5, while it is highly interactive and requires front-end development to master JS. It is recommended to learn H5 first and then gradually learn JS. H5 mainly learns tags and is easy to get started; JS is a programming language with a steep learning curve and requires understanding of syntax and concepts, such as closures and prototype chains. In terms of pitfalls, H5 mainly involves compatibility and semantic understanding deviations, while JS involves syntax, asynchronous programming and performance optimization.

Which one is easier to learn, H5 or JS? This question is awesome, just like asking “what is easier to use, screwdriver or hammer”, depending on what you want to do. To put it simply, H5 is the canvas and JS is the brush. You have to learn to use a brush before you can create something on the canvas. So, from the perspective of learning curve, the threshold for JS is slightly higher.

H5, the full name HTML5, is essentially a markup language, which defines the structure and semantics of web page content. You only need to learn some tags, such as <p></p> , <h1></h1> , <img alt="Which is easier to learn, H5 or JS?" > , etc., to build a simple web page. It's more like a specification that tells the browser how to display content. The learning cost is low and it is fast to get started. You can create a simple web page in three days. This feels very good and full of accomplishment. But this also means that H5 itself has limited expressive ability, and it can only describe "what is" and cannot describe "how to do it".

JS, that is, JavaScript, is the real programming language. It gives web pages the ability to interact dynamically, making web pages "move". You can use JS to manipulate web elements, process user input, send network requests, and even do some complex animation effects. It's like learning a new language that requires mastering concepts such as grammar, data types, functions, objects, etc. The learning curve is relatively steep and requires a certain programming foundation, or in other words, a certain logical thinking ability. You have to spend time understanding the concepts of closures and prototype chains, and write elegant and efficient code, which is not achieved overnight.

For example, you want to make a simple counter. With H5 you can only display numbers, and JS can make this number change with the button click. It's like H5 provides you with a stage, and JS gives this stage vitality.

So, if you want to quickly build a static web page, learning H5 is enough. But if you want to develop interactive web applications, or want to deepen the front-end development direction, JS must be mastered. In fact, many times, you have to learn H5 and JS at the same time, which complement each other.

Let’s talk about the pitfalls. There are few pitfalls in H5, mainly because of some browser compatibility issues and some tag semantics bias. There are many pitfalls in JS. From simple syntax errors to complex asynchronous programming, to performance optimization, each stage will encounter various challenges. For example, for JS asynchronous operations, if you do not understand the concepts of callback functions, Promise, async/await, it is easy to write code that is difficult to maintain and debug. Also, JS prototype chains and closures are also places that many beginners are prone to be confused.

My advice is to start with H5 first, quickly build a sense of accomplishment, and then gradually learn JS. During the learning process, practice more, check more documents, read more excellent code, think more when encountering problems, try more, and don’t be afraid of making mistakes. Remember, programming is a craft, and practice makes perfect. Continue to learn and accumulate, and you will become a master.

Finally, I'll give you a piece of code, a simple JS counter, used in the H5 page:

 <code class="html">   <title>JS Counter</title>   <p>Count: <span id="count">0</span></p> <button onclick="increment()">Increment</button> <script> function increment() { let count = parseInt(document.getElementById("count").textContent); count ; document.getElementById("count").textContent = count; } </script>  </code>

This is just a simple example, but it reflects the essence of the combination of H5 and JS. If you think about it carefully, you will understand the mystery. Keep working hard!
