How to disable multiple rules for eslint nextline

Question

I have this code:

const subTotal = orderInfo.details.reduce((acc, cv) => acc += Number(cv.price) * Number(cv.quantity), 0);

I want to disable two ESLint types of checks for this line, no-return-assign and no-param-reassign .

I tried it this way:

/* eslint-disable-next-line no-return-assign eslint-disable-next-line no-param-reassign */
const subTotal = orderInfo.details.reduce((acc, cv) => acc += Number(cv.price) * Number(cv.quantity), 0);

But my editor is still showing the eslint(no-return-assign) lint error.

Answer 1

If you want to disable multiple ESLint errors, you can do the following (note the commas):

• For the next line:

// eslint-disable-next-line no-return-assign, no-param-reassign
( your code... )

• For this line:

( your code... ) // eslint-disable-line no-return-assign, no-param-reassign

• Or alternatively for an entire code block (note that this only works with multi-line comment syntax) :

/* eslint-disable no-return-assign, no-param-reassign */
( your code... )
/* eslint-enable no-return-assign, no-param-reassign */

See the Configuring Rules section of the ESLint documentation.

(Though it might be a better choice to simply disable these errors in your .eslintrc file if you can't follow certain rules all the time.)

Answer 2

You should use commas instead.

/* eslint-disable-next-line no-return-assign, no-param-reassign */
const subTotal = orderInfo.details.reduce((acc, cv) => acc += Number(cv.price) * Number(cv.quantity), 0);
