Are H5 and JS learning costs high?

The cost of learning H5 and JS depends on the basis, objectives and learning methods. For those with zero foundation, there are certain thresholds: HTML5 focuses on label mastery, CSS cultivates layout perception, and JavaScript includes a variety of programming paradigms and requires abstract capabilities. But rich learning resources, hands-on practices, learning partners and clear goals can reduce learning costs. Code examples show the charm of JS functions and event handlers. Persistence, summary and enjoyment of the process is the key to learning programming.

Are H5 and JS learning costs high? This question is well asked! To put it directly or not is too arbitrary. It's like asking "Is it difficult to climb Mount Everest?", depending on your foundation, goals and learning methods.

For novices with no foundation, there is indeed a certain threshold. HTML5 itself has a relatively clear structure and is not too difficult to understand, but it takes time to practice to master various tag attributes and semantics. CSS is more like an art, you need to develop a sense of layout and aesthetics in order to write a pleasing page. JavaScript is a behemoth, which includes various programming paradigms such as functional programming, object-oriented programming, asynchronous programming, etc. It requires certain logical thinking ability and abstract ability to understand. You have to spend time understanding the concepts of prototype chains, closures, and event loops. It's a big deal to think about it.

However, this does not mean that learning H5 and JS is destined to be an ascetic.

First of all, the learning resources are very rich. There are countless tutorials, documents, and videos online, and various learning platforms also provide a large number of courses. You can find resources that suit your learning rhythm and style. Don’t be scared by those courses that cost hundreds of hours. The key is to find a learning path that suits you and proceed step by step.

Secondly, practice brings true knowledge. Just reading books and videos is not enough. You must type in code and do projects. Start with a simple static page, gradually increase the interaction effect and constantly challenge yourself. Don’t be afraid of making mistakes. Programmers’ daily routines are debugging. Learning from mistakes is the fastest way to grow.

Then, find a study partner or join the study community. Learning with others can encourage each other, help each other, and solve problems more efficiently. In the community, you can reach more experienced developers and learn their ideas and skills.

Finally, don't forget to set goals. What are you learning H5 and JS for? Want to make a web game? Or do you want to develop a web application? The clearer the goal, the stronger the motivation to learn and the higher the learning efficiency.

Regarding the code, I will show you a simple example to experience the charm of JS:

 <code class="javascript">//一个简单的函数，计算两个数字的和function sum(a, b) { return ab; } //调用函数并输出结果console.log(sum(5, 3)); //输出8 //一个简单的事件监听器，当点击按钮时，改变文本内容const button = document.getElementById("myButton"); const text = document.getElementById("myText"); button.addEventListener("click", function() { text.textContent = "按钮被点击了！"; });</code>

This code is simple, but it shows the core functionality of JS: function and event processing. Learning JS is to constantly learn and master more and more complex functions and event handling methods, and how to cleverly combine them to achieve the functions you want.

In short, the cost of learning H5 and JS depends on the effort you put in and how you learn. As long as you persist in learning, persevere, and be good at summarizing and reflecting, you can overcome the difficulties in learning and eventually become an excellent web developer. Remember, learning programming is a long-term process, you must be patient and even more passionate! Don't forget to enjoy the process!
