+# babel-plugin-transform-regexp-constructors
+
+This changes RegExp constructors into literals if the RegExp arguments are strings.
+
+## Example
+
+**In**
+
+```javascript
+const foo = 'ab+';
+var a = new RegExp(foo+'c', 'i');
+```
+
+**Out**
+
+```javascript
+const foo = 'ab+';
+var a = /ab+c/i;
+```
+
+## Installation
+
+```sh
+npm install babel-plugin-transform-regexp-constructors
+```
+
+## Usage
+
+### Via `.babelrc` (Recommended)
+
+**.babelrc**
+
+```json
+{
+  "plugins": ["transform-regexp-constructors"]
+}
+```
+
+### Via CLI
+
+```sh
+babel --plugins transform-regexp-constructors script.js
+```
+
+### Via Node API
+
+```javascript
+require("@babel/core").transform("code", {
+  plugins: ["transform-regexp-constructors"]
+});
+```
