6.22.0 (2017-01-19)

Thanks to 10 new contributors! (23 total)

A quick update since it's been over a month already: adds support for shorthand import syntax in Flow + some fixes!

We'll be merging in our current 7.0 PRs on a 7.0 branch soon and I'l be making some more issues (most should be beginner-friendly).

To follow our progress check out our 7.0 milestone, the wiki and upcoming announcements on twitter!

We support stripping out and generating the new shorthand import syntax in Flow (parser support was added in babylon@6.15.0. 

import {
  someValue,
  type someType,
  typeof someOtherValue,
} from "blah";

🐛 Bug Fix

  • babel-plugin-transform-object-rest-spread 
const { x, ...y } = foo();

Old Behavior 

const { x } = foo();
const y = _objectWithoutProperties(foo(), ["x"]);

New/Expected Behavior 

const _ref = foo(); // should only be called once
const { x } = _ref; 
const y = _objectWithoutProperties(_ref, ["x"]);
  • babel-cli
  • babel-plugin-transform-object-rest-spread

Accounts for default values in object rest params 

function fn({a = 1, ...b} = {}) {
  return {a, b};
}
  • babel-plugin-transform-es2015-destructuring 
const assign = ([...arr], index, value) => {
  arr[index] = value
  return arr
}

const arr = [1, 2, 3]
assign(arr, 1, 42)
console.log(arr) // [1, 2, 3]
