/**
* \t\t it's a test function
*/

/**
* it's a test function
*/
function test(){}

var x = 1; // test

Options

This rule has an optional object option with the following properties:

• allowIndentationTabs (default: false): If this is set to true, then the rule will not report tabs used for indentation.

allowIndentationTabs

Examples of correct code for this rule with the allowIndentationTabs: true option:

/* eslint no-tabs: ["error", { allowIndentationTabs: true }] */

function test() {
\tdoSomething();
}
