Chaining Promises

Chaining Promises is a technique used in JavaScript programming language to handle asynchronous operations. It involves linking multiple promises together to execute them in a specific order. Promises are objects that represent the eventual completion or failure of an asynchronous operation and allow us to write asynchronous code that looks synchronous. Chaining Promises allows us to execute multiple asynchronous operations in a specific order, where the output of one operation is used as the input of the next operation. This technique helps to avoid callback hell and makes the code more readable and maintainable. In Chaining Promises, we can attach a .then() method to a promise, which takes a callback function as an argument. The callback function receives the resolved value of the previous promise as its argument. We can also attach a .catch() method to handle any errors that occur during the execution of the promise chain.
