exersise #7 Basic: Recursion code bug

[Gordiievskyi]

If example you suggest is used for producing the expected result then it if I am not mistaken it has a bug.

1. function reduce(arr, fn, initial) {
2. return (function reduceOne(index, value) {
3. if (index > arr.length - 1) return value // end condition return reduceOne(index + 1, fn(value, arr[index], index, arr)) // calculate & pass values to next step })(0, initial) // IIFE. kick off recursion with initial values }

Row number 3 has to be updated to : if (index > = arr.length - 1) return value // end condition module.exports = reduce

Below is output of expected result input and solution:

input: [ 'enim', 'enim', 'cupidatat', 'fugiat', 'sunt', 'ullamco', 'occaecat', 'amet', 'laborum', 'ipsum', 'dolor', 'elit', 'incididunt', 'ea', 'laborum', 'nostrud', 'cupidatat', 'ipsum', 'veniam', 'ipsum', 'quis', 'anim', 'occaecat', 'tempor', 'cupidatat', 'deserunt', 'qui', 'aute', 'laboris', 'magna', 'in' ] submission: { enim: 2, cupidatat: 3, fugiat: 1, sunt: 1, ullamco: 1, occaecat: 2, amet: 1, laborum: 2, ipsum: 3, dolor: 1, elit: 1, incididunt: 1, ea: 1, nostrud: 1, veniam: 1, quis: 1, anim: 1, tempor: 1, deserunt: 1, qui: 1, aute: 1, laboris: 1, magna: 1 } solution: { enim: 2, cupidatat: 3, fugiat: 1, sunt: 1, ullamco: 1, occaecat: 2, amet: 1, laborum: 2, ipsum: 3, dolor: 1, elit: 1, incididunt: 1, ea: 1, nostrud: 1, veniam: 1, quis: 1, anim: 1, tempor: 1, deserunt: 1, qui: 1, aute: 1, laboris: 1, magna: 1, in: 1 }

As you can see there is a word : 'in' that is missing in the solution output and present in my version.
