(5 Questions)

  • Q1. What is node js express js and normal ds question based on javascipt
  • Q2. What is asynchorneion
  • Ans. 

    Asynchrony is the ability of a system to handle multiple tasks concurrently without blocking the main thread.

    • Asynchrony allows tasks to run independently of each other, improving performance and responsiveness.

    • Node.js uses an event-driven, non-blocking I/O model to handle asynchronous operations.

    • Examples of asynchronous operations in Node.js include reading files, making network requests, and executing database queries

  • Q3. What is spilt methode
  • Ans. 

    The split() method is used to split a string into an array of substrings based on a specified separator.

    • The split() method takes a separator as an argument, which can be a string or a regular expression.

    • The method returns an array of substrings created by splitting the original string at each occurrence of the separator.

    • Example: 'hello world'.split(' ') will return ['hello', 'world']

  • Q4. What is deep copy
  • Ans. 

    Deep copy is a copy of an object that duplicates all of its properties and nested objects, creating a new independent copy.

    • Deep copy creates a new object with all properties and nested objects copied.

    • Changes made to the original object do not affect the deep copy.

    • Deep copy is often used when you need to modify an object without affecting the original.

  • Q5. What is diff bw == and===
  • Ans. 

    The '==' operator checks for equality, while the '===' operator checks for strict equality (including data type).

    • The '==' operator performs type coercion before comparing two values.

    • The '===' operator does not perform type coercion and compares both value and data type.

    • Example: 1 == '1' will return true, but 1 === '1' will return false.
