Question

Accepted Answer

ES6 features, arrow functions, promises vs async/await, time complexity in JavaScript.

ES6 features include arrow functions, template literals, destructuring, spread/rest operators, etc.
Arrow functions have a more concise syntax and do not bind their own 'this' value.
Promises are objects representing the eventual completion or failure of an asynchronous operation.
Async/await is a syntactic sugar for working with promises, making asynchronous code look synchronous.
Time complexity in JavaScript refers to the efficiency of algorithms in terms of input size.
