API

sortNumbers(numbers)

numbers: Array of Number without NaN
Return: Array of Number

It returns the array numerically sorted in ascending order.

Note that Array.prototype.sort works as lexical sort by default.

var arr = [100, -2, -Infinity];

sortNumbers(arr); //=> [ -Infinity, -2, 100 ]
arr.sort(); //=> [ -2, -Infinity, 100 ]

It returns an empty array when the argument is an empty array.

It throws a TypeError when the array contains non-number values or NaN.

sortNumbers(new Array()); //=> []

sortNumbers([1, '2', 3]); // throw a type error
sortNumbers([NaN]); // throw a type error

sortNumbers.desc(numbers)

numbers: Array of Number without NaN
Return: Array of Number

It returns the array numerically sorted in descending order.

var arr = [0, 1, 2 ,3];

sortNumbers.desc(arr) //=> [3, 2, 1, 0]
sortNumbers(arr) //=> [0, 1, 2, 3]

sortNumbers.asc(numbers)

An alias to sortNumbers.
