Get Permutations Algo Recursion - I don't get it help

getPermutations.js

// Without Repetitions

function getPermutations(options) {
	const permutations = []
	console.log("FN START")
	console.log(options)

	if (options.length === 1) {
		return [options] // return statement doesn't seem to break out of function why?
	}

	const partialPermutations = getPermutations(options.slice(1)) // this seems to get skipped after return statement on line 9

	console.log("AFTER RECURSIVE STEP") // but then we go here why?
	console.log(partialPermutations)

	const firstOption = options[0]

	console.log("FIRST OPTION")
	console.log(firstOption)

	for (let i = 0; i < partialPermutations.length; i++) {
		const partialPermutation = partialPermutations[i]
		console.log("OUTER LOOP")
		console.log(partialPermutation)

		for (let j = 0; j <= partialPermutation.length; j++) {
			const permutationInFront = partialPermutation.slice(0, j)
			const permutationAfter = partialPermutation.slice(j)
			permutations.push(
				permutationInFront.concat([firstOption], permutationAfter)
			)
		}
	}

	return permutations
}

const todoListItems = [
	"walk the dog",
	"clean the toilet",
	"buy groceries",
	"order food",
	"do homework"
]

console.log(getPermutations(todoListItems))

// Time Complexity: O(n!) => 4 * 3 * 2 * 1 = 24; 5 * 4 * 3 * 2 * 1 = 120
