get-min

Get the minimum of two numbers that works the way you would expect.

It takes two anything and returns the lesser number of the two. Thats it.

example

var getMin = require('get-min');

getMin(0, 1); // 0
getMin('a', 1); // 1
getMin(1, null); // 1
getMin(1, undefined); // 1
getMin(1, Object(0)); // 1
getMin(1); // 1

getMin('1', '2'); // undefined
getMin('a', null); // undefined
getMin(); // undefined

why?

Getting the minimum of a number and garbage should be simple. It's a number that should be returned.

This example would normally require you to initialize num=10 if you were to use Math.min.

var num;

for (var i = 10; i >= 0; i--) {
  num = getMin(num, i);
};

// num = 0

vs.

var num;

for (var i = 10; i >= 0; i--) {
  num = Math.min(num, i);
};

// num = NaN   // whoops!
