### Adding a new plugin to support (when approved in the next ECMAScript version)
|
|
|
|
#### Update [`pluginFeatures.js`](/data/plugin-features.js)
|
|
|
|
Example:
|
|
|
|
In you were going to add `**` which is in ES2016:
|
|
|
|
Find the relevant entries on [compat-table](kangax.github.io/compat-table/):
|
|
|
|
`exponentiation (**) operator`
|
|
|
|
Find the corresponding babel plugin:
|
|
|
|
`transform-exponentiation-operator`
|
|
|
|
Add add them in this structure:
|
|
|
|
```js
|
|
// es2016
|
|
"transform-exponentiation-operator": {
|
|
features: [
|
|
"exponentiation (**) operator",
|
|
],
|
|
},
|
|
```
|
|
|
|
#### Update [`plugins.json`](/data/plugins.json)
|
|
|
|
Until `compat-table` is a standalone npm module for data we are using the git url
|
|
|
|
`"compat-table": "github:kangax/compat-table#gh-pages",`
|
|
|
|
So we update and then run `npm run build-data`. If there are no changes, then `plugins.json` will be the same.
