I started this journey on 2023-02-27 with a basic knowledge of computer programming.
When I see a web page and look at the "source code", I am wondering how the web page works. Now, after 11 weeks of study, I found that the JavaScript coding is the "source" that does most things to the web page behind the scenes.
Moving forward with JavaScript, I learned essential skills on creating documents with HTML, styling/positioning the documents' content with CSS, and using JavaScript to respond to events.
Breaking down the JavaScript part of web programming into three "pillars" that constitute the heart of web programming:
1) Recognizing events.
2) Manipulate DOM.
3) Communicate with server.
One interesting thing I learned about copying an array nondestructively (leaving the original array intact) is using the map method to copy an array, as in this example:
The way that JavaScript works to manipulate HTML and CSS in real-time allows for the creation of dynamic and interactive web pages, enhances the user experience, and makes web pages more engaging.
In conclusion, JavaScript is a versatile and powerful language that is essential for building modern web applications. Its ease of use, support for OOP and functional programming, and vast ecosystem of libraries and frameworks make it a popular choice for developers worldwide. Whether you are a beginner or an experienced developer, learning JavaScript is a must if you want to build dynamic and interactive web applications.
