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.

Install it:

npm install @nodetom/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(arr): returns the first index of each element of an array.
• tail(arr): returns every element but the first element of an array.
• middle(arr): returns the value/s of the middle element/s of an array.
• map(array, callback): returns a new array based on callback function given.
• letterPositions(sentence): returns indices of given character in a string.
• flatten(arr): returns a single level array when given multi level arrays.
• findKeyByValue(obj, val): returns the key of an object where that key's value matches the value given.
• findKey(obj, callback): returns the first key of an object where callback returns a truthy value.
• eqObjects(object1, object2): returns true if two objects are equal.
• eqArrays(arr1, arr2): returns true if two arrays are equal.
• countOnly(allItems, itemsToCount): counts a subset of items based on conditions given.
• countLetters(string): returns the count of each letter used in a string.
• assertObjectsEqual(obj1, obj2): returns true if two objects are equal.
• assertEqual(actual, expected): returns true if two values of primitive data types are identical in type and value.
• assertArraysEqual(arr1, arr2): returns true if two arrays are equal.
• without(sourceArr, itemsToRemove): returns a subset of an array without the unwanted elements.
• takeUntil(array, callback): returns slice of array starting at the beginning of the array until the condition is met.
