  • Q2. What is event loop

    The event loop is a core component of Node.js that enables non-blocking I/O operations by managing asynchronous callbacks.

I applied via Referral and was interviewed before Sep 2020. There were 3 interview rounds.

Interview Questionnaire 

1 Question

  • Q1. Tell me about event loop in javascript and asynchronous programming?
  • Ans. 

    Event loop in JS manages the execution of code and handles asynchronous tasks.

    • JS is single-threaded, so event loop helps manage tasks without blocking the main thread.

    • Asynchronous programming allows non-blocking execution of code.

    • Callbacks, Promises, and Async/Await are common ways to handle asynchronous tasks.

    • Example: setTimeout() function uses event loop to execute code after a specified delay.
