// Looking for more useful JavaScript methods to implement? These are  
// harder than the ones that came before, but I know you can do it.



/**  SPLICE  **/
// Modifies an array by removing a number of elements and 
// inserting any number of new ones.

// Example Usage:
// var arr = [6, 7, 8, 9];
// arr.splice(2, 1, 14, 16);  --> returns [8] and arr is now [6, 7, 14, 16, 9]

var splice = function(array, start, count) {

};


/**  SPLIT  **/
// The opposite of `join`, returns an array by breaking up a string 
// using a separator. The separators are not included in the array.

// Example Usage:
// "hello world".split(" ");    --> returns ["hello", "world"]

var split = function(string, separator) {

};


/**  MATH.SQRT  **/
// How *do* you find the square root of a number if you don't have `Math`?

// Example Usage:
// Math.sqrt(4);    --> returns 2

var sqrt = function(number) {

};


/**  DATE.PARSE  **/
// A little function that takes a date string in a variety of formats and 
// returns the number of milliseconds since midnight UTC January 1, 1970.
// Note that while the native version sometimes defaults to your local 
// time zone, the paleo version is should always default to UTC.

// Example Usage:
// Date.parse("December 12, 1990");    --> returns 660960000000

var parse = function(date) {

};
