Examples

removeDuplicates

import { removeDuplicates } from "helper-box";

// Array Example
const numbersArray = [1, 2, 2, 3, 4, 4, 5];
const uniqueNumbers = removeDuplicates(numbersArray);
console.log(uniqueNumbers);
// Output: [1, 2, 3, 4, 5]

// String Example
const text = "aabbccddeeff";
const uniqueText = removeDuplicates(text);
console.log(uniqueText);
// Output: "abcdef"

// Object Example
const object = { a: 1, b: 2, c: 2, d: 3, e: 1 };
const uniqueObject = removeDuplicates(object);
console.log(uniqueObject);
// Output: { a: 1, b: 2, d: 3 }

arrayToObject

import { arrayToObject } from "helper-box";

const users = [
  { id: 1, name: "Alice", age: 25 },
  { id: 2, name: "Bob", age: 30 },
  { id: 3, name: "Charlie", age: 35 },
];

const usersObject = arrayToObject(users, "id");

console.log(usersObject);
// Output:
// {
//   "1": { id: 1, name: "Alice", age: 25 },
//   "2": { id: 2, name: "Bob", age: 30 },
//   "3": { id: 3, name: "Charlie", age: 35 }
// }

omitKeys

import { omitKeys } from "helper-box";

const user: User = {
  id: 1,
  name: "Alice",
  age: 25,
  email: "alice@example.com",
};

// Omit 'email' and 'age' keys from the user object
const userWithoutEmailAndAge = omitKeys(user, ["email", "age"]);
console.log(userWithoutEmailAndAge);
// Output: { id: 1, name: "Alice" }

difference

import { difference } from "helper-box";

const array1 = [1, 2, 3, 4, 5];
const array2 = [4, 5, 6, 7];

// Get the difference between array1 and array2
const arrayDiff = difference(array1, array2);
console.log(arrayDiff);
// Output: [1, 2, 3] (Items from array1 not in array2)

const string1 = "hello";
const string2 = "world";

// Get the difference between string1 and string2
const stringDiff = difference(string1, string2);
console.log(stringDiff);
// Output: "he" (Characters in string1 not in string2)

const user1 = {
  id: 1,
  name: "Alice",
  email: "alice@example.com",
};

const user2 = {
  id: 1,
  name: "Alice",
};

// Get the difference between user1 and user2
const objectDiff = difference(user1, user2);
console.log(objectDiff);
// Output: { email: "alice@example.com" } (Keys in user1 not in user2)

formatCurrency

import { formatCurrency } from "helper-box";

const amount1 = 1000;
const formattedAmount1 = formatCurrency(amount1, "en-US", "USD");
console.log(formattedAmount1);
// Output: "$1,000.00" (Formatted currency for USD in en-US locale)

const amount2 = 1500;
const formattedAmount2 = formatCurrency(amount2, "de-DE", "EUR");
console.log(formattedAmount2);
// Output: "1.500,00 €" (Formatted currency for EUR in de-DE locale)

const amount3 = 2500;
const formattedAmount3 = formatCurrency(amount3);
// Output: "$2,500.00" (Formatted currency for USD in the default en-US locale)
console.log(formattedAmount3);

getQueryParams

import { getQueryParams } from "helper-box";

import { getQueryParams } from "helper-box";

// Example URL
const url1 = "https://example.com/?name=Alice&age=25&country=USA";

// Get query parameters from the URL
const params1 = getQueryParams(url1);
console.log(params1);
// Output: { name: "Alice", age: "25", country: "USA" }

const url2 = "https://example.com/?search=book&page=2&sort=asc";

// Get query parameters from the URL
const params2 = getQueryParams(url2);
console.log(params2);
// Output: { search: "book", page: "2", sort: "asc" }

💖 Support my projects

I open-source almost everything I can, and I try to reply everyone needing help using these projects. Obviously, this takes time. You can integrate and use these projects in your applications for free! You can even change the source code and redistribute (even resell it).

However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it:

• Starring and sharing the projects you like 🚀
• If you're feeling especially charitable, please follow avisek123 on GitHub.
