## README

`@ltd/j-ts`
===========

```shell
npm install @ltd/j-ts
```

`@ltd/j-ts` vs `typescript`
---------------------------

### `input.ts`

```TypeScript
	type T = any;
	
	function * f (v :T) :T {
		return <T> v as T;
	}
	
```

### `require('@ltd/j-ts')(input :string, jsx :( (name :string, context :object) => string ) | boolean = false, fileName? :string)`

```JavaScript
	             
	
	function * f (v   )    {
		return     v     ;
	}
	
```

(The error thrown for `input` will have a `index :number` property.)  
（对 `input` 抛出的错误，会带上 `index :number` 属性。）  

### `require('typescript').transpileModule(input :string, options :object).outputText`

```JavaScript
function* f(v) {
    return v;
}
```
