@habizat/lotide NPM

Lotide

A mini clone of the Lodash library.

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 @habizat/lotide

Require it:

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

Call it:

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

The following functions are currently implemented:

assertArraysEqual(array1, array2): asserts that two arrays are equal
assertEqual(actual, expected): compares the two values and prints out a message telling if they match or not
assertObjectsEqual(object1, object2): helps test functions that return objects
countLetters(sentence): returns a count of each of the letters in that sentence
countOnly(allItems, itemsToCount): takes in a collection of items and returns counts for a specific subset of those items
eqArrays(array1, array2): returns true or false, based on a perfect match of given arrays
eqObjects(object1, object2): returns true or false, based on a perfect match. Objects's values are limited to primitive values and arrays.
findKey(object, callback): returns the first key for which the callback returns a truthy value
findKeyByValue(object, value): returns the first key which contains the given value
head(array): returns first element in an array
letterPositions(sentence): returns all the indices in the string where each character is found
map(array, callback): returns a new array based on the results of the callback function
middle = function(array): returns the middle-most element(s) of the given array
tail(array): returns 'tail' of an array
takeUntil(array, callback): keeps collecting items from a provided array until thecallback provided returns a truthy value
without(source, itemsToRemove): returns a subset of a given array, removing unwanted elements
