# `constructor`
The `constructor` attribute is used to indicate that the function being bound
should actually translate to calling the `new` operator in JavaScript. The final
argument must be a type that's imported from JavaScript, and it's what will get
used in the generated glue:
```rust
#[wasm_bindgen]
extern "C" {
type Shoes;
#[wasm_bindgen(constructor)]
fn new() -> Shoes;
}
```
This will attach a `new` static method to the `Shoes` type, and in JavaScript
when this method is called, it will be equivalent to `new Shoes()`.
```rust
// Become a cobbler; construct `new Shoes()`
let shoes = Shoes::new();
```
