Can you explain the difference between synchronous and asynchronous code in JavaScript?
Sure! Synchronous code executes in sequence, while asynchronous code allows other operations to run while waiting for a task to complete.
Can you give me an example of synchronous code?
Absolutely! A simple example of synchronous code is using a for loop to process an array. Each iteration waits for the previous one to finish.
What about an example of asynchronous code?
An example of asynchronous code is using setTimeout
. It allows you to run a function after a specified delay without blocking the execution of subsequent code.
How do promises fit into asynchronous JavaScript?
Promises are a way to handle asynchronous operations. They represent a value that may be available now, or in the future, or never.
