		## Notes

		* Replacements are only applied to expressions. Therefore replacing `DEBUG` with `false` in `const DEBUG = true` does nothing, but for `if (DEBUG) {}` the result is `if (false) {}`.

		* Only full expressions count. You can't replace `env` in `process.env.NODE_ENV`, you have to replace `process.env`, which is a proper expression in Babel AST.

		* A replacement is only applied when the result is valid JavaScript. For example replacing `a` with `2` in the following code:

		```js
		a = 1;
		b = a;
		```

		yields

		```js
		a = 1;
		b = 2;
		```
