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 @ryan_williams/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): Logs to the console an assertion that the arrays are equal or are not equal.
• assertEqual(a, b): Logs ot the console an assertion that two primitive datatypes either match or do not match using ===.
• assertObjectsEqual(obj1, obj2): Logs to the console an assertion if two objects match or do not match.
• countLetters(string): Counts the charcters in a string, disregarding spaces.
• countOnly(allItems[array], itemsToCount[object]): Searches the allItems array for the keys in the itemsToCount object, counts there occurances for keys with value true.
• eqArrays(arr1, arr2): Checks if two arrays match and returns a boolean.
• eqObjects(ob1, ob2): Checks two objects match and returns a boolean.
• findKeyByValue(obj, value): searches for a value amonst an objects values and returns the key string on the match'
• findKey(obj, callback): takes an object and a callback, checks the object against the callback and returns the property where the callabck === true
• flatten(array): takes in an array with nested arrays and returns it as a single level array
• head(array): returns the first element of array without mutating the original
• letterPositions(string): returns an object of key:value pair where the key is a character, and the value is how many times that char appears in the string.
• map(array, callback): takes in an array and a callback and returns a new array with the callback applied to each element;
• middle(arr): takes in a array and returns the value or values of the middle indexs
• tail(arr): takes in an array and returns an array that is identical but without the first element.
• takeUntil(arr, callback): take in an array and a condition, will push elements to anew array until condition is met, will return that new array.
• without(arr, arr): takes in 2 arrays, will return a new array identical to arr1 without the elements listed in arr2.
