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');

It's the \/ in [-A-Z0-9+&@#\/%?=~_|!:,.;] and [-A-Z0-9+&@#\/%=~_|] (NOT the ones in :\/\/). Most characters do not have to be escaped within a character class (square brackets). This should be equivalent: /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#/%?=~_|!:,.;]*[-A-Z0-9+&@#/%=~_|])/ig See https://www.regular-expressions.info/charclass.html for more info, but the relevant part:

In most regex flavors, the only special characters or metacharacters inside a character class are the closing bracket ], the backslash , the caret ^, and the hyphen -. The usual metacharacters are normal characters inside a character class, and do not need to be escaped by a backslash. To search for a star or plus, use [+*]. Your regex will work fine if you escape the regular metacharacters inside a character class, but doing so significantly reduces readability.

//eslint-disable-next-line

place this above the line of code

OR

/*eslint no-undef: 0*/

place this on the first line of the file(or first line of the script tag) this would make eslint disabled on the whole file
