### IDL Code Samples
IDL code samples have been relocated to [this directory](https://github.com/MatthewZito/IDL/blob/master/examples)
### Compiling to JavaScript (and optimizing)
IDL:
```
(resolver(){
let (a = 2) {
let (a = 3) {
print(a);
};
print(a);
};
})();
```
JavaScript (pre-optimization):
```
(function ε_CC(ε_K1) {
STACK_GUARD(arguments, ε_CC);
(function ε_CC(ε_K2, a) {
STACK_GUARD(arguments, ε_CC);
(function ε_CC(ε_K3, a) {
STACK_GUARD(arguments, ε_CC);
print((function ε_CC(ε_R4) {
STACK_GUARD(arguments, ε_CC);
ε_K3(ε_R4)
}), a)
})
((function ε_CC(ε_R5) {
STACK_GUARD(arguments, ε_CC);
print((function ε_CC(ε_R6) {
STACK_GUARD(arguments, ε_CC);
ε_K2(ε_R6)
}), a)
}), 3)
})
((function ε_CC(ε_R7) {
STACK_GUARD(arguments, ε_CC);
ε_K1(ε_R7)
}), 2)
})
((function ε_CC(ε_R8) {
STACK_GUARD(arguments, ε_CC);
ε_R8
}))
```
Post-optimization:
```
(function (ε_K1) {
var a, ε_K3, ε_a$1;
((a=2), ((ε_K3 = (function (ε_R5) {
print(ε_K1, a)
})), ((ε_a$1=3),
print((function (ε_R4) {
ε_K3(ε_R4)
}), ε_a$1)))) })((function (ε_R8) {
ε_TOPLEVEL(ε_R8)
}));
```
