namastey-array

namastey-array is a JavaScript package that provides various important methods for working with arrays. This package includes functionality for manipulating and querying arrays with ease.

Features

• append(value): Adds a new element to the end of the array.
• insertAt(value, index): Inserts a new element at a specified position.
• remove(value): Removes an element by its value.
• find(value): Finds the index of an element by its value.
• getSize(): Returns the size of the array.
• printArray(): Prints the array to the console.
• sortArray(): Sorts the array in ascending order.
• reverseArray(): Reverses the order of the array.
• includes(value): Checks if the array includes a specific value.
• map(callback): Applies a callback function to each element and returns a new array.
• filter(callback): Applies a callback function to each element and returns a new array with elements that pass the test.
• reduce(callback, initialValue): Applies a callback function to each element to reduce the array to a single value.

Installations

You can install the package globally using npm:

npm install -g namastey-array

Examples

const NamasteyArray = require('namastey-array');

// Create a new instance with an initial array const arr = new NamasteyArray([10, 20, 30]);

// Append an element arr.append(40);

// Insert an element at a specific position arr.insertAt(15, 1);

// Print the array arr.printArray(); // Output: [10, 15, 20, 30, 40]

// Get the size of the array console.log('Size of array:', arr.getSize()); // Output: Size of array: 5

// Remove an element arr.remove(20);

// Print the updated array arr.printArray(); // Output: [10, 15, 30, 40]

// Find the index of an element console.log('Find 30:', arr.find(30)); // Output: Find 30: 2

// Sort the array arr.sortArray(); arr.printArray(); // Output: [10, 15, 30, 40]

// Reverse the array arr.reverseArray(); arr.printArray(); // Output: [40, 30, 15, 10]

// Check if the array includes a value console.log('Includes 15:', arr.includes(15)); // Output: Includes 15: true

// Map over the array const mappedArray = arr.map(x => x * 2); console.log('Mapped Array:', mappedArray); // Output: Mapped Array: [80, 60, 30, 20]

// Filter the array const filteredArray = arr.filter(x => x > 20); console.log('Filtered Array:', filteredArray); // Output: Filtered Array: [40, 30]

// Reduce the array to a single value const sum = arr.reduce((acc, x) => acc + x, 0); console.log('Sum of Array:', sum); // Output: Sum of Array: 90
