Why is the computer printing the string onto the screen?

var str = "Hello, playground"

And already it's printed onto the screen? How does the computer know you want to print it? You only declared a variable?

In C++, it won't print it onto the screen. You have to tell the computer to print it, using printf or cout<<.

I'm confused, can someone explain this to me? Or is this just a new way of doing things?

And also, there is no ending declaration after -> playing" Like in C++ you have to use a semi-colon.

Ugh, first lesson and I'm already super confused! haha

The reason you see 'Hello, playground' on the screen is because it is showing you the value of the variable, println will print to the console. If you go to view, then open the assistant editor the console will open.
