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 @maryan/lotide
Require it:
const _ = require('@maryan/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(actual, expected): that compares two arrays, actual and expected for equality using the eqArrays function. -
assertEqual(actual, expected): compares two values, actual and expected, for equality. -
assertObjectsEqual(actual, expected): compares two values, actual and expected, for equality -
countLetters(string): function that takes a string as input and counts the occurrences of each letter. -
countOnly(allItems, itemsToCount): counts the occurrences of specific items in an array and returns the count as an object. -
eqArrays(array1, array2): checks if two arrays are equal, accounting for nested arrays. -
eqObjects(object1, object2): checks if two objects are equal, accounting for nested objects and arrays. -
findKey(object, callback): searches for the first key in an object that satisfies a given condition defined by a callback function. -
findKeyByValue(inputObject, valueToFind): finds the key associated with a specific value in an object. -
flatten(arr): converts a nested array into a single-level array. -
head(array): retrieves the first element of an array. -
index: list of all the functions in an object. -
letterPositions(sentence): generates an object that stores the indices of each letter in a given sentence. -
map(array, callback): creates a new array by transforming each element of the input array using a callback function. -
middle(array): retrieves the middle element(s) of an array. -
tail(array): retrieves every element except the head (first element) of an array. -
takeUntil(array, callback):returns a portion of the array until the callback condition is met. -
without(source, itemsToRemove): creates a new array by removing specific items from the source array.
