Lotide

A mini clone of the Lodash library.

Purpose

BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.

This project was created and published by me as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @miguelaugusto/lotide

Require it:

const _ = require('@miguelaugusto/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• head(array): Returns the first element of an array.
• tail(array): Returns the last element(s) of an array as separate values, not in an array.
• middle(array): Returns the middle element(s) of an array. If the array length is odd, it returns a single middle element; if even, it returns the two middle elements.
• eqArrays(array1, array2): Checks if two arrays are equal in value and length.
• assertEqual(actual, expected): Asserts whether two primitive values are equal.
• assertArraysEqual(actual, expected): Asserts whether two arrays are equal.
• assertObjectsEqual(actual, expected): Asserts whether two objects are equal in structure and value.
• countLetters(sentence): Returns an object with counts of each letter in a given sentence.
• countOnly(allItems, itemsToCount): Returns an object containing counts of specified items from a provided list.
• eqObjects(object1, object2): Checks if two objects are equal in structure and value.
• findKey(object, callback): Returns the first key for which the callback function returns a truthy value.
• findKeyByValue(object, value): Returns the key of a given value in an object.
• letterPositions(sentence): Returns an object with arrays containing the indices of each letter in a given sentence.
• takeUntil(array, callback): Returns a slice of an array until the callback returns a truthy value.
• without(source, itemsToRemove): Returns a new array with elements from the source array that are not present in the itemsToRemove array.
