Unexpected token on object spread

Apologies if this is for the wrong project since I haven’t been able to do a direct 6to5 transform on the command line but this works in the 6to5 REPL.

In test.js:

var props = {a: 1, b: 2, c: 3};
var {a, ...other} = props;

I get the error

test.js:2 var { a, …other } = props; ^ ParseError: Unexpected token

Using the command browserify .\test.js -t [6to5ify --experimental --playground --whitelist es7.objectSpread] --outfile bundle.js

I’ve tried various combinations of the experimental, playground, and whitelist settings but to no avail.

Am I missing something?

In case of useful, here’s a snippet from my build script:

...
var b = browserify({
  cache: {},
  packageCache: {},
  plugin: [watchify],
  entries: ["./js/index.js"],
  debug: true
}).transform("babelify", {
    presets: ["es2015", "react", "stage-2"]
  }).on('update', bundle)
    .on('log', log);
...

I think what @oguzbilgic was referring to is this: http://babeljs.io/docs/usage/options/

Adding stage-2 preset solved this problem for me. These links may be useful to others walking this path: https://babeljs.io/docs/plugins/ http://babeljs.io/docs/plugins/preset-stage-2/
