import { StringBuilder, emptyString, joinString, formatString, isNullOrWhiteSpace } from 'typescript-string-operations'; // 1. Using emptyString console.log('Empty String:', emptyString); // Output: Empty String: // 2. Using isNullOrWhiteSpace const value1 = null; const value2 = ''; const value3 = ' '; const value4 = 'Hello'; console.log(`isNullOrWhiteSpace(${JSON.stringify(value1)}):`, isNullOrWhiteSpace(value1)); // Output: true console.log(`isNullOrWhiteSpace(${JSON.stringify(value2)}):`, isNullOrWhiteSpace(value2)); // Output: true console.log(`isNullOrWhiteSpace(${JSON.stringify(value3)}):`, isNullOrWhiteSpace(value3)); // Output: true console.log(`isNullOrWhiteSpace(${JSON.stringify(value4)}):`, isNullOrWhiteSpace(value4)); // Output: false // 3. Using formatString with indexed arguments const userId = '2db5da20-1c5d-4f1a-8fd4-b41e34c8c5b5'; const formattedImageName = formatString("image_{0}.jpg", userId); console.log('Formatted Image Name:', formattedImageName); // Output: image_2db5da20-1c5d-4f1a-8fd4-b41e34c8c5b5.jpg // 4. Using formatString with specifiers and objects interface Fruit { type: string; color: string; shippingDate: Date; amount: number; } const fruit: Fruit = { type: "apple", color: "RED", shippingDate: new Date(2018, 1, 1), amount: 10000 }; const fruitDescription = formatString("The {type:U} is {color:L} shipped on {shippingDate:s} with an amount of {amount:n}", fruit); console.log('Fruit Description:', fruitDescription); // Output: The APPLE is red shipped on 2018-01-01T00:00:00 with an amount of 10.000 // 5. Using joinString const joinedFruits = joinString("; ", "Apple", "Banana", "Orange"); console.log('Joined Fruits (args):', joinedFruits); // Output: Apple; Banana; Orange const fruitArray = ['Mango', 'Pineapple']; const joinedFruitArray = joinString(", ", fruitArray); console.log('Joined Fruits (array):', joinedFruitArray); // Output: Mango, Pineapple const objectToJoin = { Name: "Foo", Value: "Bar", ID: "123" }; const joinedObject = joinString('.', objectToJoin); console.log('Joined Object:', joinedObject); // Output: Foo.Bar.123 // 6. Using StringBuilder const sb = new StringBuilder(); sb.Append('Hello').Append(' ').AppendLine('World!'); sb.AppendFormat('The answer is {0}.', 42); console.log('StringBuilder Output:\n', sb.ToString()); /* Expected Output: Hello World! The answer is 42. */
