(7 Questions)
- Q1. What is hoisting in javascript
- Ans.
Hoisting is a JavaScript mechanism where variables and function declarations are moved to the top of their scope.
Variables declared with var are hoisted to the top of their scope
Function declarations are also hoisted to the top of their scope
Function expressions are not hoisted
Hoisting can lead to unexpected behavior and bugs
Example: console.log(x); var x = 5; // Output: undefined
- Q2. Explain callback hell
- Ans.
Callback hell is a situation where multiple nested callbacks make the code difficult to read and maintain.
It occurs when callbacks are nested within other callbacks.
It can lead to code that is difficult to read and maintain.
It can be avoided by using promises or async/await.
Example: fs.readFile('file.txt', function(err, data) { fs.writeFile('file2.txt', data, function(err) { console.log('File written!'); }); });
- Q3. Difference between let, var, and const keyword
- Ans.
let, var, and const are JavaScript keywords used for declaring variables with different scopes and mutability.
var is function-scoped and can be redeclared and reassigned
let is block-scoped and can be reassigned but not redeclared
const is block-scoped and cannot be reassigned or redeclared
Use const for values that won't change, let for values that will, and var for legacy code or global variables
- Q4. Difference between == and ===
- Ans.
The difference between == and === is that == compares values while === compares both values and types.
The == operator performs type coercion before comparing values.
The === operator does not perform type coercion and compares both values and types.
Using === is generally considered safer and more reliable.
Example: 5 == '5' returns true, but 5 === '5' returns false.
- Q5. Explain async, await, and promises
- Ans.
Async, await, and promises are JavaScript features used for handling asynchronous operations.
Promises are objects that represent the eventual completion or failure of an asynchronous operation.
Async/await is a syntax for writing asynchronous code that looks like synchronous code.
Async functions always return a promise.
Await can only be used inside an async function and it waits for the promise to resolve or reject befo...
- Q6. Explain the use of the $ sign in JQuery
- Ans.
The $ sign in JQuery is a shorthand for the JQuery function.
The $ sign is used to select elements in JQuery.
It can also be used to create new elements.
It is a shorthand for the JQuery function.
Example: $('p') selects all the paragraphs on a page.
- Q7. Rate yourself in Javascript and JQurey
- Ans.
I rate myself 8/10 in Javascript and 7/10 in jQuery.
Proficient in using vanilla Javascript to create dynamic and interactive web pages
Experience in using jQuery to simplify DOM manipulation and event handling
Familiarity with popular Javascript frameworks like React and Angular
Continuously learning and improving my skills in Javascript and jQuery

- Ans.
Calculate the N-th term of a Geometric Progression series given the first term, common ratio, and term position.
Use the formula A * R^(N-1) to find the N-th term of the GP series.
Remember to return the result modulo 10^9 + 7 as the term can be very large.
Handle multiple test cases efficiently by iterating through each case.

- Ans.
Find and return the value of (i * i + j * j) for elements in a 2D array where the sum of the cubes of its digits equals the element itself.
Iterate through the 2D array and check if the sum of the cubes of digits equals the element itself.
Calculate (i * i + j * j) for elements that satisfy the condition.
Return the calculated values as a new 2D array.
If no element satisfies the condition, return -1.

Exampl...
- Ans.
Calculate the number of distinct subsequences in a string with possible duplicates.
Use dynamic programming to keep track of the count of distinct subsequences for each character in the string.
Consider the cases where the current character is included or excluded in the subsequence.
Handle duplicates by using a hashmap to store the last occurrence index of each character.
Modulo the final count by 10^9 + 7 to avoid overfl

- Ans.
Remove the Kth node from the end of a singly linked list given the position from the end to be removed.
Traverse the list to find the length 'N' of the linked list.
Calculate the position from the beginning to be removed as 'N - K + 1'.
Delete the node at the calculated position from the beginning.
- Q3.
Common Elements Problem Statement
Identify and output the common strings present in both given arrays of lowercase alphabets for each test case.

The task is to find common strings in two arrays of lowercase alphabets for each test case.
Iterate through the elements of the second array and check if they are present in the first array.
Use a hash set to store the strings of the first array for efficient lookup.
Return the common strings in the order they appear in the second array.
Interview Preparation Tips
Tip 1 : If you have time for your interviews, I would recommend going through Leetcode as it has a good variety of questions sorted on topic wise difficulty level where you can try to solve at least 20-30 questions for each data structure and algorithm. Moreover, you should regularly participate in the weekly contests happening there so that you could know about your weak areas to improve.
Tip 2 : Practice DSA everyday and make sure that you are giving timed mock tests periodically.
Tip 3 : Keep revising your Computer Science fundamentals(OS, DBMS, Software Engineering principles).
Tip 4 : Also brush-up your aptitude skills.
Tip 1 : The most important tip is that never lie on your resume and like If you have worked upon some technology for the project part only and don't know the proper depth you could write basics only in your resume.
Tip 2 : Customize your resume for a company based on their Job Description (highlight necessary skills)
Tip 3 : Include only those points about which you're fully confident. Sometimes including too much increases expectations and then the bar is set high for you which impacts the assessment
Tip 4 : Don't put anything in resume that you are not sure of.
Tip 5 : if you don't have any internship experience then you can show your good technical projects and certifications too.
