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.

/**
|
|
* Creates a new list iteration function from an existing one by adding two new
|
|
* parameters to its callback function: the current index, and the entire list.
|
|
*
|
|
* This would turn, for instance, [`R.map`](#map) function into one that
|
|
* more closely resembles `Array.prototype.map`. Note that this will only work
|
|
* for functions in which the iteration callback function is the first
|
|
* parameter, and where the list is the last parameter. (This latter might be
|
|
* unimportant if the list parameter is not used.)
|
|
*
|
|
* @func
|
|
* @memberOf R
|
|
* @since v0.15.0
|
|
* @category Function
|
|
* @category List
|
|
* @sig ((a ... -> b) ... -> [a] -> *) -> ((a ..., Int, [a] -> b) ... -> [a] -> *)
|
|
* @param {Function} fn A list iteration function that does not pass index or list to its callback
|
|
* @return {Function} An altered list iteration function that passes (item, index, list) to its callback
|
|
* @example
|
|
*
|
|
* const mapIndexed = R.addIndex(R.map);
|
|
* mapIndexed((val, idx) => idx + '-' + val, ['f', 'o', 'o', 'b', 'a', 'r']);
|
|
* //=> ['0-f', '1-o', '2-o', '3-b', '4-a', '5-r']
