A method is a function that belongs to the object. Methods have a "receiver" while functions do not.
const someObject = {
someMethod: function () {
console.log('Hello, World!');
},
};
// method call
someObject.someMethod(); // `someObject` is a receiver, `someMethod` is a method
const someFunction = someObject.someMethod;
// function invocation
someFunction(); // JavaScript functions are invoked without a receiver, using parenthesis syntax
function helloWorld() {
console.log('Hello, World!');
}
helloWorld(); // logs "Hello, World!"
// When a function is declared on the global scope, it becomes a property of a global object
// The `window` is the receiver of `helloWorld,` which would make `helloWorld` a method and not a function. However, in JavaScript, it is still considered a function.
window.helloWorld(); // logs "Hello, World!"
