Now it is time to bring in a callback. A callback is a function passed as an argument to another function. Using a callback, you could call the calculator function (myCalculator) with a callback (myCallback), and let the calculator function run the callback after the calculation is finished:
In computer programming, a callback is programming pattern in which a function reference is passed from one context (consumer) to another (provider) such that the provider can call the function.
A callback function, also known as a higher-order function, is a function that is passed to another function as a parameter, and the callback function is called (or executed) inside the parent function.
A callback function is a function passed into another function as an argument, which is then invoked inside the outer function to complete some kind of routine or action.
A callback function is a function that is passed as an argument to another function and executed later. A function can accept another function as a parameter. Callbacks allow one function to call another at a later time. A callback function can execute after another function has finished.
You can do this using JavaScript's callback functions, which showcase JavaScript's ability to handle asynchronous operations. Let's explore what callback functions are, how they work, and why they're essential in JavaScript.
A callback function in JavaScript is a function that’s called after the first function has completed its task. Learn more about how they’re used and when to use them.
A callback function is a function that is passed into another function as an argument and is executed at a later time. The function that accepts the callback is usually responsible for executing it once a particular task is completed.
A function that does something asynchronously should provide a callback argument where we put the function to run after it’s complete. Here we did it in loadScript, but of course it’s a general approach.
