Greetings
I have a question about methods in javascript. Can anyone tell me if this is a method and what kind of method this is.
nomeMetodo : function (){
//code
}
It wouldn’t be like this...
function nomeMetodo () {
//code
}

The two ways are right.
javascript works with the concept of anonymous function, is called anonymous precisely because you do not need to define a name to it, as below.
function (){
//code
}
This anonymous function will usually be used when you need to assign the function to a variable
var nomeMetodo = function (){
//code
}
or create a function in an object:
var x = {
a: 2,
nomeMetodo: function() {
return this.a;
}
}
In this case if you call x.nameMetodo() it will return the value of a
Everything will depend on how you use your function... if you want to know a little more, I recommend starting with MDN documentation.

I should add your answer that there is a difference in declaring a function, and assigning a function to a variable. See https://stackoverflow.com/questions/336859/var-functionname-function-vs-function-function_functionname

It’s a yes method. With literal objects, we can invoke functions the way you exemplified them. Read about objects. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Tworksworks_com_Objetos#Definindo_m%C3%A9all

The first is a Method, you use it inside an object, in this case
nomeMetodowould be a property of the object whose value is a function. The second is a Function normal.– LeAndrade
