|
---
|

# Description
|
|
|
|
The `delete` operator deletes a binding (duh).
|
|
|
|
# Syntax
|
|
|
|
``` javascript
|
|
let anObject = { left: 1, right: 2 };
|
|
console.log(anObject.left); // 1
|
|
|
|
delete anObject.left;
|
|
|
|
console.log(anObject.left); // undefined
|
|
console.log("left" in anObject); // false
|
|
console.log("right" in anObject); // true
|
|
```
