(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

- Q1. Difference between sorting algorithms
- Ans.
Sorting algorithms are methods used to arrange elements in a specific order.
Different sorting algorithms include bubble sort, selection sort, insertion sort, merge sort, quick sort, and heap sort.
Some algorithms are more efficient than others depending on the size of the data set and the initial order of the elements.
For example, quick sort is generally faster than bubble sort for large data sets.
- Q2. BFS and DFS in trees and imlementing them
- Ans.
BFS and DFS are traversal algorithms used in trees. BFS explores level by level, while DFS explores depth first.
BFS (Breadth-First Search) visits nodes level by level, using a queue. Example: traversing a binary tree level by level.
DFS (Depth-First Search) explores as far as possible along each branch before backtracking. Example: in-order traversal of a binary tree.
