# babel-plugin-transform-remove-undefined
For variable assignments, this removes rvals that evaluate to `undefined`
(`var`s in functions only).
For functions, this removes return arguments that evaluate to `undefined`.
## Example
**In**
```javascript
let a = void 0;
function foo() {
var b = undefined;
return undefined;
}
```
**Out**
```javascript
let a;
function foo() {
var b;
return;
}
```
## Installation
```sh
npm install babel-plugin-transform-remove-undefined --save-dev
```
## Usage
### Via `.babelrc` (Recommended)
**.babelrc**
```json
{
"plugins": ["babel-plugin-transform-remove-undefined"]
}
```
### Via CLI
```sh
babel --plugins babel-plugin-transform-remove-undefined script.js
```
### Via Node API
```javascript
require("@babel/core").transform("code", {
plugins: ["babel-plugin-transform-remove-undefined"]
});
```
## Options
+ `tdz` - Detect usages before declaration/initialization in let/const(throws) and var(void 0)
