# babel-plugin-transform-strict-mode

Add the `"use strict";` directive to the top of your files if it is not there
|
|
already.
|
|
|
|
> This plugin may be enabled via `babel-plugin-transform-es2015-modules-commonjs`.
|
|
> If you wish to disable it you can either turn `strict` off or pass
|
|
> `strictMode: false` as an option to the commonjs transform.
