Are structures in swift the same as objects in javascript?

I am comming from an extensive background in javascript(Angularjs/React.js) and I am now learning swift. I see that structures are closely related to objects in javascript.

My question is .. Are structures (struct) the same as objects in javascript and if not what advantages does one have over the other?

Moises, I'll get this started and hopefully others can fill in. A struct in Swift is a complex data type that can have variables and methods associated with it. You can create instances of the struct (like you would create instances of your JS object). A struct is also a 'value type' . This means that if you copy a struct, when you make a change to one copy, it does not affect the other copy (this behavior is unlike that of a class, which is a reference type - when you copy an instance of a class (i.e. create an object) both copies reference the same data). A struct also does not have inheritance like a class would. I'm not very familiar with JS to say if the object in JS is acting like a class in Swift (i.e. is a reference type). Hopefully others can expand on this information.
