		# bind-decorator
		The best automatic context method binding decorator

		- It will `throw` exceptions if decorating anything other than `function`, [run this](throws.md);
		- Since the implementation follows the latest `decorator`s [purposal](http://tc39.github.io/proposal-decorators/) where compartion betweeen `this` and `target` can not be trusted, [run this if you don't belive me](not-comparable.md). `@bind` will always `return` a `configurable`, `enumerable` `get accessor propertyDescriptor` with value of `descriptor.value.bind(this)`.
		Context method binding decorator.

		In fact the whole implementation is just 12 lines of code:
		`@bind` is just a little faster version of [`@autobind`](https://github.com/andreypopp/autobind-decorator/blob/master/src/index.js) for decorating methods only, by binding them to the current context. It is written in TypeScript and follows the latest `decorator`s [purposal](http://tc39.github.io/proposal-decorators/).

		```typescript
		export function bind<T extends Function>(target: Object, propertyKey: string \| symbol, descriptor: TypedPropertyDescriptor<T>): TypedPropertyDescriptor<T> \| void {
		if(!descriptor \|\| (typeof descriptor.value !== 'function')) throw new TypeError(`Only functions can be decorated with @bind. <${propertyKey}> is not a function!`);

		return {
		configurable: true,
		get(): T {
		return descriptor.value.bind(this);
		}
		};
		}
		- It will `throw` exceptions if decorating anything other than `function`;
		- Since the implementation follows the latest `decorator`s [purposal](http://tc39.github.io/proposal-decorators/) where compartion betweeen `this` and `target` can not be trusted, `@bind` will always `return` a `configurable`, `get accessor propertyDescriptor` which will memomize the result of `descriptor.value.bind(this)` by re-defining the property descriptor of the method beeing decorated (Credits goes to [autobind-decorator](https://github.com/andreypopp/autobind-decorator/blob/master/src/index.js) for memoizing the result).

		export default bind;
		```
		If you are looking for not just method decorator but rather full class bounding decorator check [`@autobind`](https://github.com/andreypopp/autobind-decorator/blob/master/src/index.js).
