@ -43,11 +43,18 @@ To transpile to ES6/ES2015:
```js ```js
require("@babel/core").transform(code, { require("@babel/core").transform(code, {
"plugins": [ "plugins": [
["@babel/proposal-unicode-property-regex", { "useUnicodeFlag": true }] ["@babel/proposal-unicode-property-regex", { "useUnicodeFlag": false }]
] ]
}); });
``` ```
## Options
* `useUnicodeFlag` (defaults to `true`)
When disabled with `false`, the transform will convert unicode regexes to
non-unicode regexes, removing the `u` flag. See https://www.npmjs.com/package/regexpu-core#useunicodeflag-default-false- for more information.
