typescript-string-operations-ng4

This is a porting of "typescript-string-operations" (https://github.com/sevensc/typescript-string-operations) adapted to work correctly with angular 4 and above

jQuery required. Unit tested (work in progress).

USAGE:

String.Empty

var id = String.Empty;

String.IsNullOrWhiteSpace():

var id = image.GetId();
if(String.IsNullOrWhiteSpace(id))
    return image;

String.Format():

var id = image.GetId()
String.Format("image_{0}.jpg", id)
output: "image_2db5da20-1c5d-4f1a-8fd4-b41e34c8c5b5.jpg";

Specifier available!

var value = String.Format("{0:L}", "APPLE"); //output "apple"
 
value = String.Format("{0:U}", "apple"); // output "APPLE"
 
value = String.Format("{0:d}", "2017-01-23 00:00"); //output "23.01.2017"
 
 
value = String.Format("{0:s}", "21.03.2017 22:15:01") //output "2017-03-21T22:15:01"
 
value = String.Format("{0:n}", 1000000);
//output "1.000.000"

Specifier	Result
L	LowerCase
U	UpperCase
d	ShortDatePattern
s	SortableDateTimePattern
n	Thousand seperator

String.Join():

var value = String.Join("; ", "Apple", "Banana");
//output: "Apple; Banana";

OR

var array = ['Apple', 'Banana']
var value = String.Join("; ", array);
