JavaScript is a popular programming language that has the following characteristics: cross-platform and can run on a variety of operating systems and devices; lightweight and efficient, suitable for the development of web applications and interactive websites ; Dynamic, allowing code and data structures to be modified at runtime to achieve interactivity and dynamic response.
Three characteristics of JavaScript
As a popular programming language, JavaScript has the following three characteristics:
1. Cross-platform
JavaScript is cross-platform, which means it can run on various operating systems (such as Windows, macOS, Linux) and devices ( such as desktop computers, laptops, and mobile devices). This cross-platform nature enables developers to create applications for a wide audience without having to write separate code for each platform.
2. Lightweight and efficient
JavaScript is a lightweight and efficient language, which makes it suitable for the development of web applications and interactive websites. It can be executed directly on the client without server processing, which improves response speed and performance.
3. Dynamic
JavaScript is a dynamic language, which means it allows code and data structures to be modified at runtime. This dynamic nature provides flexibility, allowing developers to create highly interactive applications that respond dynamically to user input and events. It also allows modifications to the DOM (Document Object Model) after the page is loaded, enabling features such as form validation and dynamic content updates.
