What is the concept of outputting in base JavaScript, and how do Promises and setTimeout() function work in this context?

Question

Accepted Answer

Outputting in base JavaScript involves understanding the event loop, Promises, and asynchronous behavior with setTimeout().

JavaScript is single-threaded, using an event loop to manage asynchronous operations.
setTimeout() schedules a function to run after a specified delay, adding it to the event queue.
Promises represent a value that may be available now, or in the future, or never, allowing for cleaner asynchronous code.
Example of setTimeout: setTimeout(() => console.log('Hello'), 1000); // logs 'Hello' after 1 second.
Example of Promises: new Promise((resolve, reject) => { /* async operation */ }).then(result => console.log(result));
