title: JavaScript Delete Operator
---
# 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
```
