the reason we get this instant feedback |||||imediato| |||||natychmiastowe| |||||миттєвий| il motivo per cui otteniamo questo feedback immediato

is because typescript behaves like a |||comporta-se|| |||zachowuje|| |||поводиться|| è perché il dattiloscritto si comporta come a

likely have a ts config file ||||configuração| ||||archivo de configuración| prawdopodobnie||||ts config|

which provides an infinite number of |||infinita|número| |zapewnia||nieskończoną||

ways to customize the behavior of the ||modify|||| ||dostosować|||| ||personalizar el comportamiento|||| ||personalizar||||

compiler

but the primary goal of typescript is to ||principal|objetivo||||

enable static typing włącza||typowanie

one way it achieves that is by allowing |||alcança||||permitindo |||osiąga||||pozwalając |||logra||||

you to annotate your code with types ||Label|||| ||annotować|||| ||anotar|||| ||anotar||||

we can strongly type a variable using a ||fortemente||||| ||mocno|||||

colon followed by its type like a string colon type string||||||| dwukropek|||||||a Dos puntos||||||| dois pontos|seguido||||||string

boolean or number booleano|| boolean(1)|| boolean o número||

that's known as an explicit type if we ||||clearly defined type||| ||||jawny|||

then try to assign its value as the |||atribuir||valor|| |||przypisz||||

wrong type we get an error

alternatively if we set an initial value alternatywnie|||||początkową| |||||starting| alternativamente si establecemos|||||| alternativamente|||||inicial|

it will implicitly infer the type |||inferir implícitamente|| ||in a way|deduce|| ||implicitamente|inferir|| ||implicitnie|wnioskować||

however there may be cases where you ||||casos|| ||||przypadki||

want to opt out of this behavior ||choose to leave|||| ||optar|||| ||zrezygnować||||

in which case you can annotate with the |||||add notes||

any type that allows you to loosely type ||||||flexibly typed| ||||||libremente| |||permite|||livremente|

or opt out of type checking when working

with an array ||um array(1)

use brackets to strongly type a list in |angle brackets|||||| |colchetes (1)|||||| |corchetes||||||

addition you can define your own custom ||||||personalizado adição|||definir||sua|personalizada

types and interfaces ||interfaces

which is especially powerful when ||especialmente|poderosa|

working with objects the car interface

here defines various types |define||

of the properties on an object we can ||as propriedades|||um objeto||

then apply the interface to a plain ||||||superficie simple |||interface|||

javascript object

the beauty of having strongly typed code |||||tipado fuerte| |a beleza||||tipada|

is that we get autocomplete everywhere ||||autocompletar| ||||autocompletar|

in our ide

we don't have to jump back and forth to |||||||para trás e para frente|
