Utility Functions Library

This library provides a collection of utility functions for array operations, string manipulation, and other common programming tasks. Each function is designed to be reusable, efficient, and easy to integrate into your projects.

Installation

Install the package via NPM:

npm install utility-functions-library

Features

1. removeDuplicates

   Removes duplicate elements from an array.

2. arraySum

   Calculates the sum of all numbers in an array.

3. capitalizeString

   Capitalizes the first letter of each word in a string.

4. getUniqueElements

   Returns unique elements from an array, maintaining their first occurrence order.

5. findUnion

   Finds the union of multiple arrays.

6. chunkArray

   Splits an array into smaller chunks of a specified size.

Usage

Import the functions into your project:

const {
  removeDuplicates,
  arraySum,
  capitalizeString,
  getUniqueElements,
  findUnion,
  chunkArray,
} = require("utility-functions-library");

Examples

1. Remove Duplicates

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

2. Calculate Array Sum

   const numbers = [10, 20, 30, 40];
   console.log(arraySum(numbers)); 
   // Output: 100

3. Capitalize String

   const sentence = "hello world from javascript!";
   console.log(capitalizeString(sentence)); 
   // Output: "Hello World From Javascript!"

4. Get Unique Elements

   const items = [5, 1, 3, 5, 2, 3, 6];
   console.log(getUniqueElements(items)); 
   // Output: [5, 1, 3, 2, 6]

5. Find Union

   const array1 = [1, 2, 3];
   const array2 = [3, 4, 5];
   const array3 = [5, 6, 7];
   console.log(findUnion(array1, array2, array3)); 
   // Output: [1, 2, 3, 4, 5, 6, 7]

6. Chunk Array

   const numbers = [1, 2, 3, 4, 5, 6, 7];
   console.log(chunkArray(numbers, 3)); 
   // Output: [[1, 2, 3], [4, 5, 6], [7]]
