(5 Questions)
- Q1. Prototypical Inheritance
- Q2. Why we can't use arrow function in constructor
- Ans.
Arrow functions do not have their own 'this' value, which is required in constructors.
Arrow functions do not have a 'this' binding, so 'this' will refer to the parent scope.
Constructors require 'this' to refer to the newly created object.
Using arrow functions in constructors can lead to unexpected behavior and errors.
- Q3. Explain details about CORS
- Ans.
CORS stands for Cross-Origin Resource Sharing and is a security feature implemented in web browsers.
CORS allows web servers to specify which origins are allowed to access their resources.
It is used to prevent unauthorized access to resources on a different domain.
CORS is implemented using HTTP headers such as Access-Control-Allow-Origin and Access-Control-Allow-Methods.
It is important to properly configure CORS to avoi...
- Q4. Explain with an example about Lexical Scoping
- Ans.
Lexical scoping is a way of defining variable scope based on where they are declared in the code.
Variables declared inside a function have local scope and are not accessible outside the function.
Variables declared outside a function have global scope and can be accessed from anywhere in the code.
Nested functions can access variables declared in their parent function.
Example: function outer() { let x = 10; function inne...
- Q5. Advantages of arrow function
- Ans.
Arrow functions have concise syntax, implicit return, and lexical this binding.
Shorter syntax than traditional function expressions
Implicit return of a single expression
Lexical this binding, avoiding the need for .bind() or self = this
Example: const double = (num) => num * 2;
Example: const names = ['Alice', 'Bob', 'Charlie']; const nameLengths = names.map(name => name.length);

Expand outwards from each center to check for palindromes of odd and even lengths.

Search for the minimum element in a rotated sorted array with duplicate elements.

Consider cases where the array is not rotated or contains only one element.
- Q3. Ways of declaring singleton class
