# Emblem
**Emblem** is static language that compiles to JavaScript.
__Emblem Source__
```emblem
scope {
int l = 0
string f
l = 3 + 3 * 3
f = 'foo' * 2
bool o = true == true
o = 2 != 2 && 'foo' == 'foo'
string m = 'Hello World'
int len = #m
int i = 2
i += 4
}
```
__Resulting JavaScript__
```javascript
{
var l = 0;
var f = '';
l = 3 + 3 * 3;
f = (new Array(2 + 1).join('foo'));
var o = true === true;
o = 2 !== 2 && 'foo' === 'foo';
var m = 'Hello World';
var len = m.length;
var i = 2;
i = (i + 4);
}
```
## Development Status
The Project just started, only initial development is done.
Belows a list of upcoming milestones and their targets.
1. Milestone
- Compile in emblem runtime on demand
- Finish support for slicing operators - Done
- Support list literals and slicing - Done
- Support map literals - Done
- Map keys must be int or string or castable to any of those two - Done
- Support weakmaps?
- Add full import / export support - Halfway Done
2. Milestone
- Support ranges
- Support constant variables
- String interpolation
3. Milestone
- Add support for warnings
- warn about re-defined operators
4. Milestone
- Support if / else / elif
- Support try / except / finally
- Support forin
5. Milestone
- Support properties
- Support struct types
6. Milestone
- Support functions
- Allow for overloading call operator
Below's a extremely incomplete listing of other both done and outstanding tasks.
