@putout/plugin-declare-before-reference 
The
ReferenceErrorobject represents an error when a variable hasn't yet been initialized in the current scope is referenced.(c) MDN
πPutout 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:
- β Function declarations
- β Class declarations
- β 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-referenceRule
{
"rules": {
"declare-before-reference": "on"
}
}β Example of incorrect code
const {remove} = operator;
const {types, operator} = require('putout');β Example of correct code
const {types, operator} = require('putout');
const {remove} = operator;Comparison
