During a job interview, you're asked about the evolution of JavaScript. The interviewer specifically wants to know about a major shift in JavaScript's usage from merely adding interactivity to web pages to being used in server-side programming. What technology or platform brought about this shift?

  • Node.js
  • Apache Tomcat
  • PHP
  • Ruby on Rails
JavaScript's major shift into server-side programming was largely enabled by Node.js. Node.js is a runtime environment that allows JavaScript to be executed on the server, making it suitable for building scalable, server-side applications. It revolutionized web development by unifying front-end and back-end languages.
