typescript-string-operations's Introduction

Simple lightweight string operation library for Typescript

USAGE:

String.Empty

var id = String.Empty;

Returns an empty String. Just because we have those in C# 😉

String.IsNullOrWhiteSpace():

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

Returns a boolean that indicates if a given string is null or contains no printable characters.

String.Format():

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

Replaces a given pattern with provided values. The value can further be formatted using the following specifiers:

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
`000`	Pad the number with zeros

String.Join()

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

OR

let array = ['Apple', 'Banana']
let value = String.Join("; ", array);
//output: "Apple; Banana";
