Disable the eslint rule for a specific line

To disable code lines, use eslint inline comments syntax.

For example, We have a code.

console.log('eslint rule disabled');

console.log('eslint example');

ESLINT rules are disabled or enabled using comment syntax.

These rules apply using single-level comments or multi comments syntax.

Syntax:

Here is a syntax for inline comments syntax

// disable/enable rule[s]

Here is a syntax for multi-line comments syntax

/*
disable/enable rule[s]
*/

We can disable single or all rules.

use eslint-disable-next-line to disable the next line of code as seen below

// eslint-disable-next-line no-use-before-define
console.log('eslint rule disabled');

console.log('eslint example');

console.log('eslint rule disabled');// eslint-disable-line no-use-before-define
console.log('eslint example');
