# disallow deleting variables (no-delete-var)
The purpose of the `delete` operator is to remove a property from an object. Using the `delete` operator on a variable might lead to unexpected behavior.
## Rule Details
This rule disallows the use of the `delete` operator on variables.
If ESLint parses code in strict mode, the parser (instead of this rule) reports the error.
Examples of **incorrect** code for this rule:
```js
/*eslint no-delete-var: "error"*/
var x;
delete x;
```
