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 a predicate and returns a pair of lists with the following properties:
|
|
*
|
|
* - the result of concatenating the two output lists is equivalent to the input list;
|
|
* - none of the elements of the first output list satisfies the predicate; and
|
|
* - if the second output list is non-empty, its first element satisfies the predicate.

* @memberOf R

* @since v0.19.0
|
|
* @category List
|
|
* @sig (a -> Boolean) -> [a] -> [[a], [a]]
|
|
* @param {Function} pred The predicate that determines where the array is split.
|
|
* @param {Array} list The array to be split.

* @example

*
|
|
* R.splitWhen(R.equals(2), [1, 2, 3, 1, 2, 3]); //=> [[1], [2, 3, 1, 2, 3]]
