Interview Questionnaire
7 Questions
- Q1. What is closure and it's applications.
- Ans.
Closure is a function that has access to variables in its outer scope, even after the outer function has returned.
A closure can be used to create private variables and methods in JavaScript.
Closures can be used to implement partial application and currying.
Event listeners and callbacks often use closures to maintain state between function calls.
Closures can be used to create memoized functions that cache their results
- Q2. What is callbacks hell, promises, observables, asynch await.
- Ans.
Callbacks hell is a situation where nested callbacks make code hard to read and maintain. Promises, observables, and async/await are solutions to this problem.
Callbacks hell occurs when there are too many nested callbacks in code.
Promises are a way to handle asynchronous operations in JavaScript.
Observables are similar to promises but can handle multiple values over time.
Async/await is a syntax for writing asynchronous
- Q3. What is higher order functions. And it's usage.
- Ans.
Higher order functions are functions that take other functions as arguments or return functions as their result.
Higher order functions allow for more flexible and reusable code.
They can be used for tasks such as filtering, mapping, and reducing arrays.
Examples include Array.prototype.map(), Array.prototype.filter(), and Array.prototype.reduce().
- Q4. What is oops in JavaScript. And difference between functional programming and OOPs.
- Ans.
OOPs in JavaScript is a programming paradigm that uses objects to represent real-world entities. Functional programming is a paradigm that uses functions to perform tasks.
OOPs in JavaScript involves creating objects that have properties and methods.
Functional programming involves creating functions that take input and produce output without modifying the input.
OOPs focuses on encapsulation, inheritance, and polymorphis...
- Q5. What is event loop and types of tasks in the queue.
- Ans.
Event loop is a mechanism that allows JavaScript to perform non-blocking I/O operations.
Event loop is responsible for handling asynchronous callbacks in JavaScript.
Tasks in the queue can be either microtasks or macrotasks.
Microtasks are executed before macrotasks.
Examples of macrotasks include setTimeout, setInterval, and I/O operations.
Examples of microtasks include Promise callbacks and mutation observer callbacks.
- Q6. Output of the code in JavaScript.
- Ans.
Output of the code in JavaScript
Need to see the code to determine output
Output can vary based on input and logic
Can use console.log() to print output
- Q7. How browser works detailed analysis.
- Ans.
