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 @stan_surj98/lotide

Require it:

const _ = require('@stan_surj98/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): Asserts strict equality between the contents of two arrays.
• assertEqual(actual, expected): Asserts strict equality between an actual value to an expected value; only supports primitive value comparisons.
• assertObjectsEqual(actual, expected): Asserts strict equality for the full value of an object to an expected object.
• countLetters(string): Counts the number of occurences of a particular letter within a string.
• countOnly(allItems, itemsToCount): Returns an array of only items provided in the second parameter.
• eqArrays(array1, array2): Returns true if two arrays are strictly identical.
• eqObjects(object1, object2): Returns true if two objects are strictly identical.
• findKey(object, callback): Takes in an object, and a callback function. Returns the key of the item passed as an argument to the callback function.
• findKeyByValue(object, callback): Takes an object and a callback. Returns the key of the value passed as an argument to the callback function.
• head(array): Returns the first element in a given array.
• letterPositions(string).[letter]: Takes in any string, and a letter as a property key. Returns an array of all the index positions where the letter occurs.
• map(array, callback): Takes in an array, and a callback. Produces a new array with the modified values passed in to the callback.
• middle(array): Takes in an array and returns another array of the value(s) of the middle element(s).
• tail(array): Takes an array, returns everything after the initial element.
• takeUntil(array, callback): Takes an array, returns everything until conditions are satisfied in the callback function.
• without(array, itemsToRemove): Takes in a source and itemsToRemove array. Returns an array without the itemsToRemove argument.
