Javascript: Callback and High Order Function

CALLBACK A callback is a function that gets invoked after an asynchronous result appears. a callback function is an async function argument. - Asynchronous code result handle using callback and promises. // callback function function with argument // ---argument :// if a function pass-through function as an argument, it is higher-order function. function needs to be called in order to execute. a callback is used when calling a function asynchronous What is a Callback or Higher-order Function? A callback function , also known as a higher-order function, is a function that is passed to another function (let’s call this other function “otherFunction”) as a parameter, and the callback function is called (or executed) inside the otherFunction. A callback function is essentially a pattern (an established solution to a common problem), and therefore, the use of a callback function is also known as a callback pattern. High-order function is a function that takes ...
