Questions and Answers

What is an interpreted programming language?

An interpreted programming language is a type of programming language that executes instructions directly, without the need for a separate compilation step, allowing for more flexibility, ease of use, rapid implementation of code changes, and examples include Python, Ruby, and JavaScript.

What are the advantages of an interpreted programming language?

Advantages include easier debugging and testing, platform independence, simpler syntax, beginner-friendliness, dynamic typing for flexibility, faster development, and access to extensive libraries and frameworks for expedited development.

What is Node.js?

Node.js is a runtime environment allowing execution of JavaScript code outside browsers, commonly used for server-side applications, networking tools, and automation, featuring an event-driven architecture, non-blocking I/O API, and a vast ecosystem of libraries through npm.

What is a runtime environment?

A runtime environment is the software and hardware infrastructure enabling program execution, providing necessary resources and services like memory allocation, input/output operations, and system calls, ensuring consistent program operation across different systems and platforms.

Question

What are the pros of using an interpreted programming language?

Answer

Pros include easier debugging, platform independence, simpler syntax, dynamic typing, and access to extensive libraries and frameworks.

Question

What are the cons of using an interpreted programming language?

Answer

Cons include slower execution speed, less efficient memory usage, potential security vulnerabilities, and limitations in scalability and performance.

Question

What is Node.js?

Answer

Node.js is a runtime environment that allows JavaScript code to be executed outside of a web browser, commonly used for building server-side applications.

Question

What is a virtual machine?

Answer

A virtual machine is a software-based emulation of a physical computer, allowing multiple operating systems to run on a single physical machine.
