Which of the following is true about JavaScript?a)It is a server-side ...
JavaScript Overview
JavaScript is a versatile programming language primarily used for web development. Understanding its capabilities is essential for developers.
Server-side vs Client-side
- Server-side scripting: JavaScript can be used on the server-side through environments like Node.js. This allows developers to write server-side applications in JavaScript, enabling back-end development.
- Client-side scripting: Traditionally, JavaScript is known for client-side scripting, where it runs in the user's browser to create interactive web pages.
Compiled vs Interpreted Language
- Compiled Language: JavaScript is not a compiled language in the traditional sense. It is primarily an interpreted language, meaning it is executed line by line at runtime by the JavaScript engine in the browser or server. However, modern JavaScript engines (like V8) optimize the execution speed by compiling to machine code, blurring the lines between interpreted and compiled languages.
Conclusion
The correct answer to the question is option 'D', which could imply that both b and c are incorrect. JavaScript can be used for both client-side and server-side scripting, and it operates as an interpreted language rather than a strictly compiled one. Understanding these aspects is crucial for effective JavaScript programming.
