Function Currying

What will be logged to the console?

const greet = (greeting) => (name) => (punctuation) => `${greeting}, ${name}${punctuation}`;

const greetInEnglish = greet('Hello');
const greetJohn = greetInEnglish('John');
const result = greetJohn('!');

console.log(result);

Hello, John!
The console will log 'Hello, John!'. This example demonstrates a three-level curried function for creating greetings. First, we create a partially applied function `greetInEnglish` by fixing the greeting to 'Hello'. Then we create another partially applied function `greetJohn` by fixing the name to 'John'. Finally, we call `greetJohn` with the punctuation '!' to get the complete greeting. This showcases how currying can be used to build specialized functions in layers, each adding a specific piece of functionality or data to create the final result.
function (punctuation) => `Hello, John${punctuation}`
Hello!John
undefined
