Variable Declarations

Introduction 🚧

TurboScript supports let const and var variable declarations. let and var has same meaning in the current version, this may change in the future versions.

var declarations

Declaring a variable in JavaScript has always traditionally been done with the var keyword.

var a = 10;

As you might’ve figured out, we just declared a variable named a with the value 10. By default it will inferred as uint32 type (this might change to int32 in future).

We can also declare a variable inside of a function:

function f():uint32 {
    var id:uint32 = 1;

    return 1;
}

const declarations

const declarations are another way of declaring variables.

const numLivesForCat = 9;

They are like let declarations but, as their name implies, their value cannot be changed once they are bound. In other words, they have the same scoping rules as let, but you can’t re-assign to them.
