Node.js exam

Quick practical exam for node.js candidates.

load tags.txt to get an array of tags
for each of these tags, find out how many times that tag appears within the objects in data/*.json (note: objects can be nested).

	/*
	Given an array of integers, calculate which fraction of its elements are positive, which fraction of its elements are negative, and which fraction of its elements are zeroes, respectively. Print the decimal value of each fraction on a new line.

	Note: This challenge introduces precision problems. The test cases are scaled to six decimal places, though answers with absolute error of up to 10−410−4 are acceptable.

	Input Format

	The first line contains an integer, NN, denoting the size of the array.
	The second line contains NN space-separated integers describing an array of numbers (a0,a1,a2,…,an−1)(a0,a1,a2,…,an−1).
