JavaScript - String Extensions #2 [ replaceAll() ]

Unfortunately function replace() in JavaScript replaces only the first matching SubString.
Here is an extension of String Type, which allows you to replace all the found SubStrings.
You can optionally specify more than one (array of strings) string to search for.

/****************************************
* String extensions
****************************************/
String.prototype.replaceAll = function (search, replace) {
    /// 
    /// Replaces all instances of [search] String or Array of Strings
    /// 
 
    var searches = [];
    if (Object.prototype.toString.call(search) === '[object Array]') {
        searches = search;
    } else {
        searches = [search];
    }
    var result = this + "";
    for (var i = 0; i < searches.length; i++) {
        result = result.split(searches[i]).join(replace);
    }
 
    return result;
};

Usage of simple replace:

var someString = "aaa-bbb-ccc-ddd";
var resultCsv = someString.replaceAll("-", ";");

Replace array of strings:

var someString = "aaa-bbb#ccc:ddd";
var resultCsv = someString.replaceAll(["-", "#", ":"], ";");

JavaScript - String Extensions #1 [ isEmpty(), left(), right(), contains(), repeat() ]

Often, when I am working with Strings in JavaScript, I need many common functions.
Such as the left(), right(), isEmpty(), contains(), ETC.
To make work easier, I wrote a few to appropriate extensions for String:

/****************************************
* String extensions
****************************************/
String.prototype.isEmpty = function () {
    /// 
    /// Check if string is empty
    /// 
    return (this.length === 0);
};
 
String.prototype.left = function (subStringLength) {
    /// 
    /// Gets left part of string
    /// 
    if (subStringLength > this.length) return this;
    return this.substring(0, subStringLength);
};
 
String.prototype.right = function (subStringLength) {
    /// 
    /// Gets right part of string
    /// 
    if (subStringLength > this.length) return this;
    return this.substring(this.length, this.length - subStringLength);
};
 
String.prototype.contains = function (subString) {
    /// 
    /// Checks if strin contains other string
    /// 
    if (this.indexOf(subString) > 0) return true;
    return false;
};
 
String.prototype.repeat = function (num) {
    /// 
    /// Repeates string [num]-times
    /// 
    if (isNaN(num)) return null;
    if (!(num > 0)) return "";
    return new Array(num + 1).join(this);
};

MSSQL - Convert list to table #1 (array of numbers in string form)

Extended version of function from this post: MSSQL - Convert list to table #2 (array of string items)
Function described here (TABLE-Value UDF) converts a string in the form "123;bbb;;;456" to tabular form.
Result will contain only non-empty items which was possible to convert to INTEGER.
In case if list has non-unique items, the function returns the serial number for each items group (RANK).

-- Drop Function if exists
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'dbo.fnArray2IntTable'))
    DROP FUNCTION dbo.fnArray2IntTable;
