100+ Aura Technologies Interview Questions and Answers

Yes, the question is asking about comparing values with type coercion in JavaScript.

• In JavaScript, the == operator compares values with type coercion, meaning it will convert the operands to the same type before making the comparison.

• For example, 1 == '1' will return true because the string '1' is converted to a number before comparison.

• However, 1 === '1' will return false because the strict equality operator (===) does not perform type coercion.

Python generator is a function that returns an iterator object which can be iterated over.

• Generators are created using a function with 'yield' statement instead of 'return'.

• Generators are memory efficient and can be used to generate an infinite sequence of items.

• Example: def my_generator(): for i in range(5): yield i

• Example: gen = my_generator() print(next(gen)) # Output:...read more

Yes, you can reverse a string in Python using slicing.

• Use the slicing syntax [::-1] to reverse a string.

• Example: 'hello'[::-1] will return 'olleh'.

REST uses fixed endpoints to define the resources that can be accessed through the API.

• RESTful APIs use fixed URLs to access resources

• Each endpoint corresponds to a specific resource or action

• Endpoints are defined in the API documentation

• Example: GET /users retrieves a list of users
