How do you disable no-plusplus when using eslint?

Question

When using eslint in Visual Studio Code, AirBnB style Ubuntu Linux, no-plusplus is enabled as default so using ++ for example in a for loop will error: [eslint] Unary operator '++' used. (no-plusplus)

How do you disable that setting?

You can just override it in your .eslintrc.js file as follows:

'no-plusplus': 'off'

or if you don't want to disable it completely but only for for-loops:

'no-plusplus': [2, { allowForLoopAfterthoughts: true }]

Do I need to surround this with anything? I'm getting this error: `(function (exports, require, module, __filename, __dirname) { 'no-plusplus': 'off' ^ SyntaxError: Unexpected token :` – Aaron Franke Jun 06 '19 at 00:08
For newer versions of ESLint, use `"allowForLoopAfterthoughts": true`, as explained on the docs: https://eslint.org/docs/rules/no-plusplus#options – goetz Jun 25 '20 at 14:49
You can simple write += 1 instead, as suggested by ESLint. – Ashish Gupta Dec 28 '20 at 14:21

You can locate the file location you need to alter on Linux by searching for the keyword using grep, in this case to search for the file containing plusplus when in the folder eslint was installed use

grep -r plusplus

The correct file will be the eslint-config file, in this case it should be: node_modules/eslint-config-airbnb-base/rules/style.js

To disable the setting comment out the no-plusplus line, you can easily re-enable if required:

// 'no-plusplus': 'error',

editing a file in node_modules shouldn't be considered the "correct way" to do something — Edo, Oct 17 '19 at 15:05

You can simply write your declared variable += 1 instead, as suggested by ESLint.

varible++ is similar as variable+=1.
