Heyy, how are you?!

Have you ever had to deal with some JavaScript functions just... they weren't exactly the way you expected? Maybe it looked like the functions were written in a different way than what you've seen and I don't mean "logically" speaking... 😅

If yes, I would like to introduce you to some possibilities of types of functions that we can find!

So, let's start it and see some basic types!

🎯 Named Function (Traditional way):

The traditional way of creating a function and it's a set of statements that performs a task or calculates a value!

function sayHello() {
  console.log('Hey everyone!');
}

sayHello();

// Output
'Hey everyone!'

🎯 Arrow Function:

Arrow Functions are simpler, are always unnamed and compact than traditional function expression!

const sayHello = () => console.log('Hey everyone!');

sayHello();

// Output
'Hey everyone!'

🎯 Anonymous Function:

Anonymous Functions don't have a name specified after the function declaration, so we declare it with a variável to call this function at a some point and the function is anonymous but assigned to a variable!

const sayHello = function () {
  console.log('Hey everyone!');
}

sayHello();

// Output
'Hey everyone!'

🎯 Higher Order Function:

Higher Order Functions in a nutshell words is a function that can take one or more functions as arguments or return a function as output. Some of Higher order types is like: reduce, filter, map and others.

// A simple function to print a console.log
function sayHello(){
  console.log('Hey everyone!');
}

// Higher Order Function Example:
function higherOrderFnExample(functionToExecute){

  console.log('I can do anything!');

  functionToExecute()
}

higherOrderFnExample(sayHello);

🎯 Constructor Function:

It's is used to create Function objects and we need to use the new keyword to create a new Function instance!

// Creating the Constructor Function
function Car () {
  this.name = 'Ford',
  this.color = 'Black'
}

// Creating the Object
const myCar = new Car();

console.log(myCar.name);
// Output
'Ford'

console.log(myCar.color);
// Output
'Black'

Hope this makes you feel a bit more comfortable with functions and their possibilities!
