Callbacks in JavaScript refer to functions that are passed as arguments to other functions. These functions are executed at a later point in time, often in response to some event or after a certain asynchronous operation completes.

myFunction is an argument in other function (callback)
sum(5, 3, displayDOM);
function sum(x, y, myFunction) {
let result = x + y;
myFunction(result);
}
function displayConsole(output) {
console.log(output);
}
function displayDOM(output) {
document.getElementById("p1").innerHTML = output;
}
