Asynchronous programming in Javascript.
- JavaScript, being single-threaded, offers asynchronous programming to handle complex tasks without blocking the script.
- Asynchronous programming in JavaScript allows the script to continue executing while waiting for tasks to complete.
- Callback functions are used in asynchronous programming to execute tasks after the main function has completed.
- Promises represent the result of an asynchronous operation in JavaScript and can be in pending, fulfilled, or rejected states.
- Promises offer a more modern approach to asynchronous programming and can be created using the Promise constructor with then and catch methods.
- Async/await is a more readable way to handle asynchronous operations in JavaScript, making code look like synchronous code.
- Async keyword is used to declare asynchronous functions, await keyword is used to wait for promises to be resolved.
- Async/await makes it easier to understand and maintain asynchronous code in JavaScript.
- Asynchronous code within an async function executes asynchronously while code outside the function executes synchronously.
- The await keyword can only be used within asynchronous functions in JavaScript.
- Understanding asynchronous programming in JavaScript is crucial for creating efficient and responsive applications.
- Asynchronous programming offers callback functions, promises, and async/await as methods to handle asynchronous tasks.
