Unused variables are generally considered a code smell and should be avoided.

Removing unused references - It prevents unused modules from being loaded at runtime, improving performance, and preventing the compiler from loading metadata that will never be used. - It prevents conflicts that may occur when trying to reference another variable.

NOTE: If you have intentionally left a variable unused, we suggest you to prefix the variable name with a _ to prevent them from being flagged by DeepSource.

Bad Practice

import fs from 'fs' // <- unused
import { readFileSync } from 'fs'

const text = readFileSync('declaration_of_independence.txt', 'utf-8')
console.log(text)

Recommended

import { readFileSync } from 'fs'

const text = readFileSync('declaration_of_independence.txt', 'utf-8')
console.log(text)
