Question

Accepted Answer

Creating add and subtract buttons using class and functional components, creating API in Node.js, and implementing debouncing and throttling in JavaScript.

To create add and subtract buttons using class based and functional based components, you can define a state variable to keep track of the current value and update it accordingly when the buttons are clicked.
For creating an API in Node.js, you can use Express.js to define routes and handle HTTP requests. You can create endpoints for different functionalities and interact with a database if needed.
Debouncing in JavaScript involves delaying the execution of a function until after a specified time interval has elapsed since the last time the function was invoked. This can be useful for handling events like input changes or scroll events to improve performance.
Throttling in JavaScript involves limiting the rate at which a function can be executed. This can be useful for scenarios where you want to limit the number of times a function is called within a certain time frame to prevent performance issues.
