# Datatypes
> **Note:** Due to the fact that Sabre currently emits javascript, static types are not needed, as of yet. They will however be introduced soon, once a statically typed backend is used.
Sabre comes with some generic data types.
## The Integer type
The `integer` datatype represents a number. The JavaScript backend interprets any integer as a `Number` type.
The `integer` datatype represents a 4 byte decimal number.
```
fn main() {
let sum = 1 + 2
let sum: int = 1 + 2
println("1 + 2 is ", sum)
}
```
```
$ sabre build main.sb -o main.js
$ node main.js
$ sabre run main.sb
1 + 2 is 3

Arrays represent a sequence of values. They can hold any number of values of a specific type.
> **NOTE:** Currently, there is no type-checking involved when creating arrays. There will be, once a type system is in place, so don't get too attached to mixing and matching element types. ;)

If you are familiar with some other programming language, the way Sabre handles variables won't surprise you.
To declare a variable, the `let` keyword is used.
To declare a variable, the `let` keyword is used. The type of the variable is infered, but can be specified explicitly.

# Contributing
The easiest way to contribute to the Sabre project is by writing code in the language. The more the language is battle-tested, the more bugs can be found and therefore the language becomes more stable.
## Getting in touch
If you want to submit a patch, file a bug, suggest a feature or have questions about something, please send a mail to the [public mailing list](https://lists.sr.ht/~garritfra/sabre) of the project.
## Fixing things and adding features
If you want to contribute to the compiler itself, the easiest way to get started is to look at the `TODO` file at the root of the project. Usually, this is where important todo items are jotted down.
You could also run the tests (`cargo test`) and see if any tests are ignored. Usually, if a bug is found in the wild, a failing but ignored test is written, so that it can be further investigated later.
## Submitting your code
Development should happen on [SourceHut](https://sr.ht/~garritfra/sabre/). If you want to contribute code, please send a patch to the [public mailing list](https://lists.sr.ht/~garritfra/sabre). If you don't feel confortable with the [patch-based workflow](https://slashdev.space/posts/patch-based-git-workflow) yet, you can also open a pull request in the [GitHub mirror](https://github.com/garritfra/sabre).

Save the file and go back to your terminal window. Now, run the following command to compile and run your program:
```
sabre build main.sb -o main.js
```
> **Note:** JavaScript is the only currently supported backend for Sabre. There will be more soon.
Now, execute the compiled program with a runtime of your choice. We will be using Node.js for this example.
```
> node main.js
Hello, world!
sabre run main.sb
```
You should see the string `Hello World!` on the screen. Congrats! You have officially written a Sabre Program!
