check-javascript-typescript-validations

Overview

The check-javascript-typescript-validations package offers essential utility functions for validating common data types and performing array operations in JavaScript and TypeScript environments. It simplifies the validation process by providing functions to check email validity, phone number formatting, password strength, and date validity. Additionally, it includes functions to determine the language of a text, check variable emptiness, and verify numeric data types. For array manipulation, the package offers functions to remove duplicates, sort arrays, and both remove duplicates and sort arrays simultaneously. These utilities enhance code quality and reliability by ensuring that data meets specified criteria, contributing to more robust applications and smoother user experiences.

Support on

JavaScript, TypeScript, React JS, React Native , Node JS, Next JS, Nest JS, etc.

// Example usage of isValidEmail
const email = "[email protected]";
console.log(isValidEmail(email)); // true

// Example usage of deepCloneArray
const originalArray = [{ id: 1 }, { id: 2 }]; 
console.log(deepCloneArray(originalArray)); // [{ id: 1 }, { id: 2 }]

// Example usage of variableIsEmpty
const emptyString = "";
console.log(variableIsEmpty(emptyString)); // true

// Example usage of isTextArabic
const arabicText = "مرحبا";
console.log(isTextArabic(arabicText)); // true

// Example usage of isTextEnglish
const englishText = "Hello";
console.log(isTextEnglish(englishText)); // true

// Example usage of checkIsNumber
const value = 123;
console.log(checkIsNumber(value)); // true

// Example usage of isValidPhoneNumber
const phoneNumber = "+1234567890";
console.log(isValidPhoneNumber(phoneNumber)); // true

// Example usage of isStrongPassword
const password = "Str0ng@Pass";
console.log(isStrongPassword(password)); // true

// Example usage of isValidDate
const date = "2021-10-10";
console.log(isValidDate(date)); // true

// Example usage of removeDuplicatesFromArray
const array = [1, 2, 2, 3, 4, 4, 5];
console.log(removeDuplicatesFromArray(array)); // [1, 2, 3, 4, 5]

// Example usage of sortArray
const unsortedArray = [5, 3, 8, 1, 2]; 
console.log(sortArray(unsortedArray)); // [1, 2, 3, 5, 8]

// Example usage of removeDuplicatesAndSortArray
const arrayWithDuplicates = [5, 3, 8, 1, 2, 3, 5]; 
console.log(removeDuplicatesAndSortArray(arrayWithDuplicates)); // [1, 2, 3, 5, 8]

// Example usage of compareTwoStrings
const str1 = "hello";
const str2 = "hello";
console.log(compareTwoStrings(str1, str2)); // true

// Example of  differenceOfTwoDates
const startDate = "2024-05-10"; // Start date format will be  *** YYYY-MM-DD ***
const endDate = "2024-05-20"; // End date format will be  *** YYYY-MM-DD ***
console.log(differenceOfTwoDates(startDate, endDate)); // {  days: 10 ,hours: 0, minutes: 0, seconds: 0 }

console.log(checkDataEmptyOrNot([])) // true <-  Empty
console.log(checkDataEmptyOrNot({})) // true <-  Empty
console.log(checkDataEmptyOrNot({a:1})) // false <- not Empty
console.log(checkDataEmptyOrNot(2)) // false <- not Empty
console.log(checkDataEmptyOrNot("abc")) // false <- not Empty
