Disable Unnecessary escape character: \/ no-useless-escape

You can use ESLint and try adding either of the things:-

1. //eslint-disable-line on the line to disable warnings.
2. //eslint-disable-next-line to line before to disable warnings.

See from docs of ESLint, Disabling Rules with Inline Comments.

To disable all rules on a specific line, use a line or block comment in one of the following formats:

alert('foo'); // eslint-disable-line

// eslint-disable-next-line
alert('foo');

/* eslint-disable-next-line */
alert('foo');

alert('foo'); /* eslint-disable-line */

You can disable warnings in entire file by adding /* eslint-disable */ at the top of the file.

To disable rule warnings in an entire file, put a /* eslint-disable */ block comment at the top of the file:

/* eslint-disable */
   alert('foo');
