📄️ callback

A callback is basically a function who is passed as an argument to another function and is executed after some operation has been completed

destructuring is a way to extract value from arrays or objects into distinct variables,

arrow functions

map

The immutability principle

with an object this, we can acess properties of the object that the current function is a method of:

Static object methods

Basically, it is a role that verifies if a function was defined before the call, if not, the calling wont occur, it avoid errors

Promises allow for asynchronous development by linearizing with callbacks

We could say that rest operator "collects" the remaining elements from a destructuring operation and saves them to a variable

Spread operator is a very useful tool
