+# @babel/plugin-proposal-throw-expressions
+
+This plugin transforms Throw Expressions into an IIFE.
+
+## Example
+
+```js
+function test(param = throw new Error('required!')) {
+  const test = param === true || throw new Error('Falsey!');
+}
+```
+
+## Installation
+
+```sh
+npm install --save-dev @babel/plugin-proposal-throw-expressions
+```
+
+## Usage
+
+### Via `.babelrc` (Recommended)
+
+**.babelrc**
+
+```json
+{
+  "plugins": ["@babel/proposal-throw-expressions"]
+}
+```
+
+### Via CLI
+
+```sh
+babel --plugins @babel/proposal-throw-expressions script.js
+```
+
+### Via Node API
+
+```javascript
+require("@babel/core").transform("code", {
+  plugins: ["@babel/proposal-throw-expressions"]
+});
+```
