es7 bind syntax

[vm]

Hey man!

Thanks for an awesome repo. Was wondering if this is currently supported?

class Hello extends React.Component {
  constructor(props) {
    super(props)
  }

  hello() {
    return "hello, " + this.props.name;
  }

  render() {
    <div>{::hello()}</div>
  }
}

Basically, that ::hello() is the same as hello().bind(this).

While testing, it seems like no. I get a red highlighting on the second :. Would love to see this working neverthless. So :+1: !

NO~

Any reference of this new spec?

[RaitoBezarius]

I could not find a spec, sorry! But there is a lot of discussion around this: http://blog.jeremyfairbank.com/javascript/javascript-es7-function-bind-syntax/ And some examples showing how to use.

And since Babel implemented it, I think that it is on its way.
