New article: String equality comparison in JavaScript
The application of object-oriented objects is quite extensive. It has appeared very early in desktop programming, and its applications are relatively mature, such as C, Java, C#, etc. As for Web programming, it appeared much later, so that current Web development is very difficult. Of course, this is also because Web development involves many technologies. In recent years, object-oriented has been gradually introduced in Web development. Many large websites are developed using PHP. The object-oriented aspects of PHP 4 are not yet perfect, but have been improved in PHP 5. .Net is also object-oriented, but its execution efficiency is not as good as PHP.
JavaScript is also used quite a lot in web development, and many commonly used form validations are completed using it. As a scripting language, JavaScript does not have a dedicated IDE development environment or good debugging tools. Its development is quite slow and it has not attracted people's attention. It wasn't until the emergence of Ajax that it was brought to life. It also allows people to truly see the effects of its combination with other technologies.
JavaScript contains object-oriented objects, but it’s just not popular in applications.
Look at a simple example:
Define CTest class // CTest.js
function CTest()
{
this.m_sStr = "";
this.Input = CTest_Input;
this.Output = CTest_Output;
function CTest_Input(str)
{
this.m_sStr = str;
}
function CTest _Output()
{
alert(this.m_sStr);
}
}
How to use
<script></script>Yes It's very similar to C++, but it's much more convenient to use. <script> <BR>var g_CTest = g_CTest = new CTest(); <BR>g_CTest.Input("Hello! Welcome to my Blog!"); <BR>g_CTest.Output(); <BR></script>

Node.js excels at efficient I/O, largely thanks to streams. Streams process data incrementally, avoiding memory overload—ideal for large files, network tasks, and real-time applications. Combining streams with TypeScript's type safety creates a powe

The differences in performance and efficiency between Python and JavaScript are mainly reflected in: 1) As an interpreted language, Python runs slowly but has high development efficiency and is suitable for rapid prototype development; 2) JavaScript is limited to single thread in the browser, but multi-threading and asynchronous I/O can be used to improve performance in Node.js, and both have advantages in actual projects.

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.
