Tim van der Lippe 16aca394c5 Update ESLint and related packages
Major update breaking changes:
- ESLint 7.0.0 (https://eslint.org/docs/user-guide/migrating-to-7.0.0) now includes
.eslint.rc.js in its list, which is fine for us. Other changes are not applicable
for us.
- eslint-plugin-mocha (https://github.com/lo1tuma/eslint-plugin-mocha/blob/master/CHANGELOG.md#700-may-13-2020)
drops support for ESLint <7, but this CL updates to 7+. Other changes are
not applicable for us.

/**
* Takes a list and returns a list of lists where each sublist's elements are
* all satisfied pairwise comparison according to the provided function.
* Only adjacent elements are passed to the comparison function.
*
* @func
* @memberOf R
* @since v0.21.0
* @category List
* @sig ((a, a) → Boolean) → [a] → [[a]]
* @param {Function} fn Function for determining whether two given (adjacent)
* elements should be in the same group
* @param {Array} list The array to group. Also accepts a string, which will be
* treated as a list of characters.
* @return {List} A list that contains sublists of elements,
* whose concatenations are equal to the original list.
* @example
*
* R.groupWith(R.equals, [0, 1, 1, 2, 3, 5, 8, 13, 21])
* //=> [[0], [1, 1], [2], [3], [5], [8], [13], [21]]
*
* R.groupWith((a, b) => a + 1 === b, [0, 1, 1, 2, 3, 5, 8, 13, 21])
* //=> [[0, 1], [1, 2, 3], [5], [8], [13], [21]]
*
* R.groupWith((a, b) => a % 2 === b % 2, [0, 1, 1, 2, 3, 5, 8, 13, 21])
* //=> [[0], [1, 1], [2], [3, 5], [8], [13, 21]]
*
* R.groupWith(R.eqBy(isVowel), 'aestiou')
* //=> ['ae', 'st', 'iou']
