🐊Putout plugin adds ability to apply declare before reference to avoid ReferenceError.

The rule is similar to ESLint's no-use-before-define, but it's auto fixable,
and ignores:

- ✅ Function declarations
- ✅ Class declarations
- ✅ Different scopes

Also it works only on top level and helps to @operator/declare with a bunch of nested declarations.

Install

``
npm i @putout/plugin-declare-before-reference
`

Rule

`json
{
"rules": {
"declare-before-reference": "on"
}
}
`

❌ Example of incorrect code

`js
const {remove} = operator;

const {types, operator} = require('putout');
`

✅ Example of correct code

`js
const {types, operator} = require('putout');

const {remove} = operator;
`
