@putout/plugin-declare-before-reference v3.0.0

@putout/plugin-declare-before-reference

The ReferenceError object represents an error when a variable hasn't yet been initialized in the current scope is referenced.

(c) MDN

🐊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

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

❌ Example of incorrect code

const {remove} = operator;

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

✅ Example of correct code

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

const {remove} = operator;
