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.

/**
|
|
* Returns a single item by iterating through the list, successively calling
|
|
* the iterator function and passing it an accumulator value and the current
|
|
* value from the array, and then passing the result to the next call.
|
|
*
|
|
* The iterator function receives two values: *(acc, value)*. It may use
|
|
* [`R.reduced`](#reduced) to shortcut the iteration.
|
|
*
|
|
* The arguments' order of [`reduceRight`](#reduceRight)'s iterator function
|
|
* is *(value, acc)*.
|
|
*
|
|
* Note: `R.reduce` does not skip deleted or unassigned indices (sparse
|
|
* arrays), unlike the native `Array.prototype.reduce` method. For more details
|
|
* on this behavior, see:
|
|
* https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reduce#Description
|
|
*
|
|
* Dispatches to the `reduce` method of the third argument, if present. When
|
|
* doing so, it is up to the user to handle the [`R.reduced`](#reduced)
|
|
* shortcuting, as this is not implemented by `reduce`.
