In JavaScript a nested type can read and assign variables from outer scopes.

function counter(start = 0) {
  let n = start;
  class Counter {
    peek() { return n; }
    increment() { ++n; }
  }
 return new Counter();

	def histogram(nums, n_buckets, title):
	min_val = min(*nums)
	max_val = max(*nums)
	buckets = []
	bucket_width = (max_val - min_val) / float(n_buckets)
	while (len(buckets) < n_buckets):
	buckets.append(0)
	sum_of_values = 0
	for num in nums:
	sum_of_values += num

	Matching code-units that have all the same size OK.
