Make jQuery collections for-of-able #1693
Comments

Isn't it a bit early to be doing this inside jQuery itself? If its just a line, the person using it knows whether their environment is going to be ES6 only. We don't know that. |

Yes, probably too early :) Just wanted to get general feedback. |
|
Hard to argue with one line of code! 😸 If you're in an environment where you know it's ES6, maybe a Phonegap/Cordova app in a year or two, it could be very handy. I don't think we'll keep this ticket open for that amount of time though? |

Agree |

I'm just going to drop this screenshot here. Once ES6 code becomes more common, this syntax comparison will be useful:

I'd love to see this. Would make using jQuery with Babel more palatable. |
|
You know, I'm not actually against this. |
|
It'd be cool to have this natively in 3.0; even if simple. :) |
|
The biggest problem is size, I guess. The following: if ( typeof Symbol !== "undefined" && Symbol.iterator ) {
jQuery.fn[Symbol.iterator] = [][Symbol.iterator];
}increases the gzipped size by 32 bytes. Other forms seem larger. |

Since there is no definite decision yet, let's reopen for now. |

The concept has already been described by @jakearchibald in Dec 2004 for NodeList: http://jakearchibald.com/2014/iterators-gonna-iterate/#nodelist-iteration |

We've decided we're going to do it in 3.0.0. I'm taking it. |
Make iterating over jQuery objects possible using ES 2015 for-of:
for ( node of $( "<div id=narwhal>" ) ) {
console.log( node.id ); // "narwhal"
}

Chrome 38 added support for ES6
for-of. I'm proposing that jQuery collections are made compatible with this statement, which can be achieved with this line (from discussion on Twitter):Live demo: http://jsbin.com/movuxu/1/edit (view in Chrome)
